How to prepare an excellent thesis defense

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

Thesis Defense: 10 Tips That Are Proven to Work

The thesis defense is a significant event in a graduate student’s journey towards getting a higher degree. Many students find this occasion daunting. But this need not be an unpleasant experience as there are ways to get rid of that uneasy feeling on that momentous day.

What preparations do you need to make your thesis defense a success? This article describes 10 tips that will give you the confidence that you need and prepare for the thesis defense adequately.

Table of Contents

Know the members of the panel in the thesis defense.

If possible, know the members of your panel, their habits, and personalities. It would be great if another graduate student had experience with those panel members to tell you how to respond to their questions.

Anticipate the questions

Example questions, dress in dark colors.

Color is an essential factor of impact. You will appear intelligent and credible if you wear black or similar color. It would help if you looked authoritative as someone who is thoroughly familiar with the topic during the thesis defense.

Get plenty of rest before your presentation

It would help if you looked confident and energetic during the thesis defense. Get enough sleep before the day of the presentation to sustain your energy while facing the panel of examiners.

Highlight the important findings of your study

Use a few (3-5) bulleted short phrases in each slide during the thesis defense. Emphasize the point using a figure, statistics, or graphics that complement the idea [Additional tip: Show updated (with the last three to five years) statistics].

Talk at moderate speed

Directly answer the question then expound a little.

Don’t beat around the bush. Go straight to the answer. Be honest if the question is not within the scope of your study. State its limitations. There will always be vague areas, but present the contribution of your research. Refer to the scope and delimitations and recommendations of your study. Ask for clarification if the question is not clear. Make sure that you address the issue of the panel.

Be thoroughly familiar with the literature that you have cited

Make sure that you are thoroughly familiar with the literature that you have cited during the thesis defense. Remember the highlights or findings of those studies as well as the limitations.

Be grateful

Always remember the one-to-one correspondence.

Ensure that for every objective that you mentioned, you have ready answers or pieces of evidence to show that you fulfilled those objectives. There should be a one-to-one correspondence in the Objectives –> Method –> Results and Discussion (includes corresponding tables or figures for each objective with explanations) –> Conclusion sections. You may prepare a matrix for each objective with the following columns for method, results and discussion, and conclusion/s.

How to Prepare for Your Dissertation Defense

4-minute read

• 1st August 2023

After years of research and study, you’ve finally reached the grand finale of your PhD years: your dissertation defense. Since defending your dissertation is the culmination of all your hard work, it’s essential to do everything you can to prepare for it.

In this post, we’ll take you through how to ready yourself for your dissertation defense so you can focus on your accomplishments and excel during this crucial professional moment.

What is a Dissertation Defense? 

The dissertation defense is the crowning moment of years of research – the final examination before a PhD student is awarded their doctoral degree.

During a dissertation defense, the student presents their research, methodology, findings, and conclusions to a committee of faculty members and experts in their field. The committee then engages in a question-and-answer session to assess the student’s understanding of the subject matter, the quality of their research, and their ability to defend their work under scrutiny.

Many PhD students consider it to be the defining moment of their academic career and their chance to prove their expertise in their chosen research field.

If all this sounds overwhelming – don’t worry. If you’re a PhD student, you’ll have plenty of time and opportunity to adequately prepare for your dissertation defense. Below are some strategies to help you get ready for this significant occasion in your career.

1.   Know the Requirements

Familiarize yourself with your institution’s guidelines and requirements for the defense process. Understanding the format, time limit, and expectations for the presentation will help you to prepare your material and anticipate any issues.

2.   Review Your Dissertation

Even if you think you know it inside and out, review your dissertation from beginning to end. It may have been some time since you’ve last read and considered certain portions of your research and findings. Consider what your committee might ask about your research questions , data analysis, and conclusions.

3.   Work on Starting Strong

To begin your defense on a strong note, work on creating a clear and engaging introduction. You can start by briefly outlining the purpose of your study, research questions, and methodology . Try to stay on topic and don’t veer off track by discussing unrelated or unnecessary information.

4.   Practice Presenting

Practice your presentation skills by rehearsing your defense multiple times. Focus on clarity and pacing and try to stay within the allotted time limit. It also helps to record yourself so that you can see yourself from your audience’s point of view.

5.   Practice Q&A Sessions

To build your confidence, enlist friends and colleagues to conduct mock question-and-answer sessions. When practicing, remember to pause before answering questions you’re unsure of. It’s better to take your time delivering a response than it is to give an inaccurate or incorrect answer.

6.   Seek Feedback

Find out if your institution offers mock defense sessions where peers or mentors play the role of the committee, ask you questions, and give feedback . You can also have colleagues, mentors, or advisors review your presentation and offer practical feedback.

7.   Create Visual Aids

Think about any visual aids , such as slides, you may want to use to illustrate your defense and prepare them in advance. Be sure to check that your university allows visuals or images and that they enhance, rather than overwhelm, your presentation.

8.   Stay Calm and Confident

It’s natural to feel nervous but try to stay calm and composed during your defense. Take deep breaths and remind yourself of the expertise you’ve gained through the experience of writing your dissertation.

The top 10 thesis defense questions (+ how to prepare strong answers)

Crafting a thesis is significant, but defending it often feels like the ultimate test. While nerve-wracking, proper preparation can make it manageable. Prepare for your thesis defense with insights on the top questions you can expect, including strategies for answering convincingly.

Mastering the thesis defense: cultivate a success mindset

Confidence enables you to present your research with conviction, while composure allows you to navigate any challenges with grace and clarity.

Remember, you know your thesis best, so trust in your expertise.

Stay composed and focused, relying on your thorough preparation. If you encounter a question you can’t answer, gracefully guide the conversation back to familiar topics.

By embracing these principles and staying confident and adaptable, you’ll navigate your thesis defense with ease.

Question 1: Why did you choose this particular topic for your research?

Moreover, discuss the gaps you identified in the existing literature that motivated you to contribute to your field. What deficiencies or unanswered questions did you observe? How did these gaps inspire you to embark on your research journey with the aim of filling these voids? By articulating the specific shortcomings in the current body of knowledge, you demonstrate a nuanced understanding of your research area and underscore the significance of your work.

Question 2: How does your research contribute to the existing body of knowledge?

This question delves into the vital role your research plays within the existing body of knowledge, urging you to articulate its significance and impact. It’s not merely about the subject matter you’ve studied, but also about the unique contributions and advancements your research brings to your field. To effectively respond, delve into the intricacies of your work and its implications for the broader academic landscape.

Illuminate how your findings could influence future research trajectories. Explore potential avenues for further inquiry that emerge from your research findings. Consider how your work opens up new questions or areas of exploration for future researchers. By identifying these potential research directions, you demonstrate the forward-looking nature of your work and its potential to shape the future trajectory of your field.

Question 3: What are the key findings of your research?

Furthermore, relate these findings to the broader implications they hold for your field. Articulate how your research contributes to advancing knowledge or addressing pressing issues within your academic discipline. Consider the potential impact of your findings on theory, practice, or policy, highlighting their relevance and significance within the larger scholarly community.

Question 4: Can you defend your research methodology?

Defending your research methodology entails a comprehensive understanding of its rationale, alignment with research objectives, and acknowledgment of potential limitations. It’s not merely about explaining the methods employed but also justifying why they were chosen over alternative approaches. To effectively respond, delve into the intricacies of your methodology and its implications for the study.

Be prepared to discuss the limitations inherent in your chosen methodology and how you mitigated them. Acknowledge any constraints or shortcomings associated with the selected approach, such as potential biases, sample size limitations, or data collection challenges. Demonstrate your awareness of these limitations and discuss the strategies implemented to address or minimize their impact on the validity and reliability of your findings.

Question 5: How did you analyze the data and what challenges did you encounter?

Begin by outlining the techniques used for data analysis. Describe the specific methods, tools, and software employed to process and interpret the data collected. Whether it involved quantitative statistical analysis, qualitative coding techniques, or a combination of both, provide insights into the analytical framework guiding your study. Additionally, discuss the rationale behind the chosen analytical approach and how it aligns with the research objectives and questions.

In summary, when addressing inquiries about data analysis, consider the following key points:

Question 6: What theoretical frameworks or references underpin your research?

Elucidate on how these frameworks shaped your hypothesis and analysis. Describe how the theoretical perspectives and insights gleaned from seminal works informed the development of your research questions, hypotheses, and analytical framework. Discuss the ways in which these theoretical frameworks guided your data collection and interpretation, influencing the selection of variables, measures, and analytical techniques employed in your study.

Question 7: How did you address ethical considerations in your research?

When addressing ethical considerations in your research, it’s essential to demonstrate a commitment to upholding ethical standards and protecting the rights and well-being of participants. Responding to inquiries about ethical protocols involves explaining the steps taken to ensure ethical conduct throughout the research process, describing the consent process and data protection measures implemented, and mentioning any institutional review board (IRB) approvals obtained.

Mention any institutional ethics review board approvals you obtained. Highlight any formal ethical review processes or approvals obtained from relevant regulatory bodies, such as IRBs or ethics committees. Discuss how the research protocol was reviewed for compliance with ethical guidelines and standards, including considerations of participant welfare, informed consent procedures, and data protection measures. By acknowledging the oversight and approval of institutional review bodies, you demonstrate your commitment to ethical integrity and accountability in conducting research involving human subjects.

Question 8: In what ways does your research contribute to the field?

Begin by detailing the novel insights your thesis provides. Articulate the key findings, discoveries, or perspectives that distinguish your research from existing literature and contribute to advancing knowledge within your field. Discuss how your study fills gaps in current understanding, challenges established assumptions, or offers innovative approaches to addressing pressing issues, highlighting its potential to generate new avenues of inquiry and broaden the scope of scholarly discourse.

In summary, when addressing inquiries about the contributions of your research to the field, consider the following key points:

Question 9: How did you ensure your research was free from bias?

Describe any blind or double-blind procedures employed in the study. Explain how blinding techniques were used to prevent bias in data collection, analysis, or interpretation. This may involve withholding certain information from researchers or participants to minimize the potential for conscious or unconscious bias to influence the results. Discuss how these procedures were implemented and their impact on enhancing the credibility and impartiality of the research outcomes.

Question 10: Where can future research go from here?

When considering the potential trajectory of your research topic, it’s essential to identify areas where further investigation could yield valuable insights, discuss unexplored questions that emerged from your research, and reflect on the limitations of your study as starting points for future research endeavors. Responding to inquiries about the future direction of research involves suggesting fruitful areas for further investigation, highlighting unresolved questions, and leveraging the limitations of your study as opportunities for future exploration.

Reflect on the limitations of your study as starting points for future research. Acknowledge any constraints, biases, or methodological shortcomings that may have influenced the outcomes or interpretations of your study. Discuss how these limitations provide opportunities for future research to refine methodologies, address confounding variables, or explore alternative theoretical frameworks. Consider how addressing these limitations could enhance the validity, reliability, and generalizability of future research findings within your field.

Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

If you want to learn more about dissertations in your own discipline, don’t hesitate to reach out to graduates from your program and ask them about their experiences.

Defend A Thesis: Prepare For Your Thesis Defense For PhD

When you’re nearing the end of your graduate program, a critical milestone looms: the thesis defense. This isn’t just a formality; it’s your chance to showcase the depth of your research and knowledge. 

In this post, we explore what is a thesis defense, the process, and how you can do well in it. 

What Is A Thesis Defense?

A thesis defense is a crucial component of completing a graduate degree, where a student presents their research findings to a panel of experts, typically comprising faculty members from their university.

This event marks the culmination of a student’s research efforts and is a formal requirement for obtaining a master’s or PhD degree.

A thesis defense is also quite similar to a dissertation defense. Both involves a student presenting their research to a panel of experts and answering in-depth questions.

The main difference typically lies in the level of study—thesis defenses are common in master’s programs, while dissertation defenses are associated with doctoral studies. Both assess the student’s research rigor and depth of knowledge.

A thesis defense is usually a nerve wrecking experience for many PhD students, but with the right knowledge and preparation, it is usually managable.

Why Must a PhD Student Defend Their Thesis / Dissertation?

There may be doctorate programs that does not require thesis defense, but PhDs generally need to do this. There are several reasons why PhD students must defend their thesis:

Demonstration of Expertise

A thesis defense compels you to consolidate your research into a coherent presentation, showcasing your depth of knowledge and critical thinking skills.

During this oral examination, you answer open-ended questions posed by a committee of faculty members. This is your chance to demonstrate that you are an expert in your field, having moved from a student to a scholar.

Mastery of Subject Matter

The defense process requires that you not only know your study’s details but also how your work fits into the broader field.

Committee members, including your advisor and other professors, will probe your understanding, asking you to justify your methodologies and conclusions.

This is akin to a rigorous job interview where your task is to convince them of your thesis’s merit.

Feedback Opportunity

This is a rare moment to receive direct, critical feedback from multiple seasoned academics. Their insights can profoundly shape the final version of your dissertation, refining your arguments and possibly influencing future research directions.

Engaging with their questions helps you think more deeply and respond to critiques that you might face when publishing your work.

Validation of Research Efforts

Defending your thesis validates your years of hard work. Successfully articulating your research process and findings in front of the defense committee is a significant accomplishment in itself.

It’s a formal acknowledgment by the academic community that your research contributes valuable knowledge and meets the rigorous standards required for a graduate degree.

Professional Preparation

The skills you hone while preparing for your defense are invaluable in any professional context, including:

• articulating complex ideas,
• responding to unexpected questions, and
• handling critique.

Whether in academic conferences, teaching scenarios, or even non-academic jobs, the ability to present and defend your ideas clearly and professionally sets you apart.

In the grand scheme, your thesis defense is more than just a formality. It’s a crucible that transforms years of research into a defended, deliberate statement of your academic capability.

It’s not just about answering questions; it’s about proving that your research stands up to scrutiny and contributes to your field.

What Happens In A Thesis Defense?

Thesis defense is a very long process. You start with months, sometimes years, of preparation, writing and completing your thesis.

You will defend your work before a committee usually made up of faculty members from your department, and possibly an external examiner. These are the experts in your field who will rigorously evaluate your research.

The defense itself is a formal yet dynamic process. It begins with you presenting your thesis, often through a detailed PowerPoint presentation. This presentation highlights:

• the main points of your research,
• your methodology, and
• your findings.

Think of it as a summary of your long journey—a chance to argue the significance and validity of your work.

After your presentation, the committee will ask questions. These aren’t just any questions; they are often complex, open-ended queries designed to test how well you understand your research and your ability to think critically under pressure.

You need to demonstrate not just knowledge, but a deep grasp of your topic and related theories.

An interesting twist is that you may be asked to leave the room after your presentation. During this time, the committee deliberates on your performance. They discuss whether you’ve met the high standards required for a PhD and whether your thesis contributes significantly to the field.

This can be a nail-biting time for many students, as the discussion behind closed doors determines the outcome of years of hard work.

If all goes well, they will call you in, and inform you that you have passed your thesis defense. At this point, you may hear yourself being addressed as a ‘Doctor’ for the first time. 

If theres hiccups, you pay still pass, but with corrections. This means you need to perform additional work on your thesis for it to be accepted. In worse cases, you thesis may require major corrections. Some examination panels may also require you to redo your thesis defense.

This is fortunately, not very common. This is because your supervisor would have ensured your work is up to par before submitting your application for thesis defense.

How To Prepare For A Thesis Defense?

Preparing for your thesis defense can be daunting. You’re about to present years of work to a committee that will scrutinize your research and knowledge. Here are ten tips to help you prepare for your thesis defense.

1. Understand the Format: Every university has its own rules for thesis defenses. Check with your advisor or the graduate office to understand exactly what’s expected of you. Whether it involves a public lecture or a closed session with your committee, knowing the format helps you prepare effectively.

2. Focus on the Core Ideas : Resist the temptation to include everything from your dissertation in your presentation. Highlight the most significant findings and methodologies. This approach helps you stay within time limits and keeps your audience engaged.

3. Anticipate Questions : Think about potential gaps in your research that faculty members might target. Prepare slides or notes that can help you answer these tough questions. This foresight can turn a difficult question into a demonstration of your thorough preparation.

4. Rehearse Extensively : Practicing your presentation multiple times is crucial. Try to simulate the defense environment as closely as possible, ideally in the actual room where you’ll present. This rehearsal will make you more comfortable and fluent during the actual defense.

5. Prepare Visually Clear Slides : Your slides should aid your presentation, not confuse the audience. Ensure they are clear, visually appealing, and free of clutter. Use diagrams, charts, and bullet points to effectively convey complex information.

6. Dress Professionally : First impressions matter. Dressing professionally respects the formality of the occasion and can also boost your confidence. A business suit is often the go to for most candidates, although some universities may be more relaxed on the dress code.

7. Create Backup Slides : Have additional slides prepared for deeper dives into specific topics. These are particularly useful if a committee member asks a detailed question about a particular point or method.

8. Know Your Committee : Research the interests and work of your committee members. This knowledge can help you anticipate the kinds of questions they might ask and prepare more targeted responses.

9. Stay Calm and Collected : Remember that defense is not just an examination but also an opportunity to showcase your work. If you don’t know an answer, it’s okay to admit this and suggest how you might find it out. This shows honesty and a willingness to learn.

10. View It as a Professional Dialogue : Approach your defense as a professional discussion rather than an interrogation. This mindset can change how you perceive the event, reducing stress and helping you engage more openly with your committee.

These strategies are about more than just surviving your defense; they’re about making the most of an opportunity to excel and impress

Prepare For Your Thesis Defense

Your thesis defense is not just a formality; it’s a bridge to your future career and a chance to shine. Prepare diligently, understanding that this is as much about demonstrating your grasp of the field as it is about honouring your own hard work.

With the right preparation, you’ll be able to defend your thesis with confidence and leave a lasting impression on your committee.

Preparing for a Successful Dissertation Defense

Everything you need to know about dissertation defense is right here: ten basic defense techniques to be ready for your academic career.

Defending your thesis is the final stretch, the finish line, and it must be handled seriously. All experiments, results analysis, and heaps of literature research lead to how well you understand your research. 

Rest assured that you are not alone if you are tormented by questions as your defense approaches. Every dissertation defense is unique, but there are strategies to prepare for this critical and significant occasion.

This article will act as a guideline with helpful tips for navigating the crucial dissertation defense phase.

What Is A Dissertation Defense?

A dissertation defense, also known as a thesis defense, is an oral presentation and discussion of a research study. The goal is to present the findings, demonstrating to the committee and the academic community that the researcher completed the work with high enough quality to be awarded a doctorate and that the researcher is capable of speaking about it without hesitation, fully understanding the work, and answering any potential questions.

It’s worth mentioning that the first step is to get the dissertation document accepted, since dissertation chairs won’t let candidates schedule defenses unless the dissertation document’s quality is completely acceptable. The purpose is to see if the researcher is prepared to defend their work.

Timing And Format

• Dissertation defenses typically require two hours of private oral examination. Depending on the institution, they may seek an additional hour for a public seminar.
• The title , as well as the written document, should be provided to the committee early on. Check the institution’s deadlines ahead of time to be prepared.
• The format might also vary depending on the institution, however, you must be prepared for an external audience as an open-to-the-public defense.

Committee Members: How To Choose And What Are The Expectations?

To align expectations, understand that the dissertation committee should support you through the process of planning, writing, and revising your dissertation; they should act as mentors, providing helpful advice and recommending modification ideas. Choose your committee carefully, it is one of the most important steps for a successful dissertation.

Avoid famous and prominent members; instead, choose someone you know well and can reach whenever you need to; and, last, choose someone you know you can learn from. 

Tips for Preparing for a Dissertation Defense

1. prepare and practice.

Before you submit your dissertation document to the committee and in between the delivery and defense event, use every time to practice and prepare yourself to defend your dissertation.

2. Know Your Weakness

Get to know your anxiety tendencies and prepare yourself around them. If you tend to talk at a quicker tempo than usual giving public speeches, you can practice a calmer rhythm. Prepare your speech and time it; this will assist you in understanding how long it should take.

3. Attend Different Presentations

Go see other dissertation defenses to help you take it more smoothly, discover tactics and how other researchers perform their speeches, and grasp the value of a dissertation defense for the community.

4. Give Yourself Enough Time To Prepare Slides

Spend some additional time crafting the perfect dissertation slides. Check that you have the right information on your slides and that your assumptions are correct to create a logical flow for your presentation. Try to start working on it as soon as you send the written document.

5. Breathing Techniques

Breathing is closely tied to oratory skills. Successful public speakers know how to regulate their breath. Try learning some breathing techniques, including long and steady breaths. 

6. Focus On A Good Introduction

It’s critical to make a strong first impression, so make sure your introduction focuses on the most important key points and that it piques your audience’s curiosity to learn more about your work.

7. Avoid Unnecessary Topics

Personal exposition should be avoided. Remember to concentrate on your work, on providing excellent research, and let go of comments implying that you worked too hard for this or that you didn’t sleep for days. Maintain a professional and clear demeanor.

8. Make Your Questions

You’ll recognize the loose ends after refining your defense multiple times. As a result, create a list of questions that come to mind when rehearsing your defense. Tip number three will also come in handy here.

9. Maintain Your Cool

You will be asked questions that you have prepared for as well as unexpected ones; this is absolutely normal, and it is quite acceptable if you don’t know the answers to all of them, since you may have opportunities for future research. While commanding your defense, maintain your cool and be confident. 

When there’s something so important on your agenda, it’s easier said than done, but you’ll be much more prepared if you get enough rest. This will make you look better, but it will also assist you in remaining focused and comfortable during your defense.

Turn Your Data Into Easy-To-Understand And Dynamic Stories

The greatest method to communicate a complex amount of data is to express it visually. Because they are easier and more effective to interpret, aids such as tables, drawings, and graphs improve the process of presenting research results. Use Mind The Graph templates to make a visual story with your data.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future . This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

Thesis Defense Steps: Full Guide How to Prepare and Present

How To Prepare For Your Thesis Defense

If you are conducting post-graduate research within your discipline, you will come across the phrase “thesis defense”. A thesis defense is part of the things you will need to accomplish before acquiring a postgraduate degree. 

The thesis defense comes at the end of the graduate program. It is used to determine or define your education milestone while in the university. For this, you need a thesis defense comprehensive guide to be outstanding.

You should do a thesis defense after you have completed the course work and attended practicum or internship programs.

How Long does a Thesis Defense Take?

On average, a thesis defense takes somewhere between 30 minutes and one hour. However, the time it takes to do a thesis defense depends on the academic level you are in.

While there is no standard or general length for a thesis defense, post-graduate sessions will take longer compared to undergraduate sessions.

Yes, some institutions, professors, or some disciplines may require you to do a thesis defense at your undergraduate level. But the length of the presentation depends on your academic level.

What is Thesis Defense?

A thesis defense is an act of presenting your academic work to a panel or committee of professors and other involved scholars. From this, they can gauge or grade your abilities in presenting your work.

The arguments presented during the thesis defense are to ascertain that you have understood the course and your selected topic.

You will have to first hand in your work or paper to the professor for grading. Thereafter, you will be summoned for thesis defense.

When summoned for a thesis defense, you will be required to answer all the questions presented to you by the panel of professors. After this, you will be required to leave the room. The panel is to decide whether your paper or thesis is ready for publication. In addition, the panel checks whether your work needs corrections. 

In other words, a thesis defense is a forum that allows postgraduate students to defend the topic of their thesis before a panel of professors. Therefore, the thesis defense is part of the requirements that postgraduate students must accomplish to receive advanced degrees in whichever academic disciplines they pursue.

Factors that Determine the Length of a Thesis Defense

Just like a dissertation that you have to write a thesis , it is important that you will have to present it. The time is taken to do this varies. The following four factors determine the length of a thesis defense

• As noted earlier, the level of education will determine the length of your thesis defense.
• The second factor is the institutional requirements. Some institutions will have a specified amount of time allocated for a thesis defense. In some institutions, that time is longer than and vice versa.

Very recognized institutions of higher learning will have the autonomy to decide on the length of a thesis defense.

• The third factor that will determine the length of a thesis defense is the consensus of the panel of professors. Some will give students very limited time to do a thesis defense while others will give more time to their students.

Some institutions, scholars, applaud limiting the amount of time for thesis defense and educators because it gauges the student’s ability to accurately defend their work within a short time. If they succeed, then they are good learners.

• Another factor determining the time of a thesis defense is the academic discipline that is explored by the topic.

While every academic discipline deserves respect, they are not the same in terms of the complexity of the concepts and what the student covers.

Some disciplines will require students to come up with much longer papers. This means that the time it could take to do a thesis defense will be longer. 

From the aforementioned factors, it is evident that it would be difficult to predetermine the standard length of a thesis without holding some parameters or factors constant such as the academic level of the thesis. 

Also, the length of your dissertation or thesis determines the time you will take to present it at your defense session. Longer documents will take you longer to defend.

How to Defend a Thesis – 5 Comprehensive Steps

Some steps can help you defend your thesis effectively. You should follow the steps below if you are summoned by a panel of professors to defend your thesis. 

1. Adequate Preparation

When you are required to defend your thesis, you will be given a specific date you will appear before the panel of professors for the actual exercise.

As long as you have submitted your paper to the professor for grading, you should always be aware that you will have to defend your thesis.

Therefore, between the period of submitting your paper and the date provided for thesis defense, you should do adequate preparation.

Students will have several months to prepare for a thesis defense. This is because the institutions themselves want their students to be well prepared before they meet the panel of professors.

After all, they would wish their students to excel in their studies. As noted, there will be a specified date for the thesis defense. Therefore, it will not surprise their committee members or students when the time comes for defending the thesis. 

Adequate preparation entails knowing or rather anticipating what is required of you. You should be prepared for the kinds of questions your thesis topic will provoke from the panel and practice on them.

When you have the right attitude and have adequately prepared for the thesis defense, it would be nearly impossible to fail. Also, be prepared to wear decently during the defense. 

2. Carry an In-Depth Knowledge of the Thesis

This is a very important step when defending your thesis. Since you are the one who has written the paper, you should be fully aware of the topic and the contents of your paper. What this means is that you should adequately research the topic of your thesis so that you can be ready for any question you are asked by the panel of professors.

For a postgraduate student who wishes to master their discipline, it would be a shame if you do not know about your topic.

For example, if you are within the field of environmental sciences and have written your paper based on the discipline, you should narrow down the scope of your knowledge to that of your topic, the topic of your paper should act as the guide to the amount of knowledge you are supposed to give for the sake of the thesis defense.

Avoid too much knowledge because it may overwhelm you. At the same time, do not narrow down the scope of your topic too much because you will have limited knowledge during the thesis defense.

Your instructor or professor can help you in terms of giving you direction on the type and scope of knowledge you are required to have during a thesis defense. 

3. Prepare an Introduction

Have you ever heard of the first impression and its significance?

The first impression of a person will determine how the other person will perceive them.

If it is terrible, the other person may consider them a terrible person and even dislike them.

An introduction plays the same role as the “first impression” of your thesis defense to the panel of professors.

You should prepare a good introduction that should summarize the contents of your paper, the reasons why you selected the topic and its relevance to the discipline, and any other detail that you will anticipate to be asked during the thesis defense.

Make sure that the thesis is crystal clear and concise to avoid making any contradictions of your topic and confusing the panel.

Since you will be given several months to prepare for your thesis defense, take time to refine your introduction.

Make adjustments or corrections whenever necessary so that you will have a perfect introduction for your thesis defense. You may recite the introduction or carry it with you if the panel will allow it. 

4. Making the Actual Presentation

The action presentation of the thesis defense is quite scary to many students. This is because you will have to face a panel of professors to defend your paper. Based on your paper’s content, you will answer several questions.

Therefore, if you fail during the actual presentation, your paper may not be published and you will have to do further revisions. 

During the actual presentation, you should be well dressed because grooming tells a lot about the character of a student. Carry the necessary equipment you will require during the presentation. Such equipment can include a laptop that contains a PowerPoint presentation, a pen, and a notebook.

The PowerPoint presentation should be legible, objective, and strategically written to maximize the time used to defend your thesis. Ensure that you arrive early to the place where you will face the panel of professors to give you time to reflect and lessen your anxiety.  

As aforementioned, adequate preparation, understanding your topic or thesis, and a good attitude will guarantee success. Therefore, if you adhere to the aforementioned guidelines during the presentation, there is a high probability that your paper will be published. 

5. Do a Good Conclusion

Doing a good introduction and effectively presenting your defense is not enough without an equally good conclusion. Just like you took a good time to write your thesis , you will also need a good time to write a presentation and a good conclusion.

A good conclusion of your presentation leaves the panel of professors with a good impression of you and your overall ability to defend your work within the academic community. 

A good conclusion will sum up your work. What this means is that you should include a summary of the topic’s background, the literature review, the methodologies, the findings, and the discussions. Make sure that the conclusion compresses the details of your paper logically. It should be brief and straight to the point.

Finally, the conclusion of your thesis defense should clearly describe the limitations or setbacks encountered while you were conducting the study.

Even though you are trying to show that you are a good post-graduate student, it is important to be clear about the limitations. This will demonstrate your academic integrity and ability to conduct actual research in the field.

Tips on How to do a Good Thesis Defense

1. Anticipate the Questions

2. Dress for Success

Do you remember that we have talked about first impressions? Well, your dress code and overall grooming will have a degree of impact on the outcomes of your presentation. Dress well.

Mostly, you are required to dress in an official attire because you are going to do a presentation to a panel of academic experts. You should try as much as possible not to wear casual or provocative clothes. 

3. Delegate

To avoid being overwhelmed during the day of your presentation, you can delegate some of the less complicated activities to a trusted person or friend.

The activities that you can delegate include setting up the equipment you will use for your presentation or distributing handouts to the panel. 

4. Create a Backup Plan

This especially involves the mode of presenting your defense. Since you will be using your laptop and a projector, they may fail during the presentation. It is therefore important to have a plan B. such can include having printed handouts.

Dissertation Defense: Steps To Follow To Succeed

A dissertation defense is arguably one of the most important milestones in every student’s career. While it signals that your tenure as a student is soon about to close, it validates all your efforts towards your thesis.

Being cautious about including all the necessary details is very important to successfully complete your dissertation proposal defense. This article tells you everything that you need to know about writing a defense that can add great credibility to you as a student.

What is A Dissertation Defense?

The first thing that you need to learn is what is a dissertation defense and what is its purpose. In simple terms, it is a presentation made by a student to defend all the ideas and views that are presented in a dissertation.

The presenter must include details like what is the reason for choosing specific research methods, the theory that has been selected for the paper, and other such points. This presentation is made before an audience that comprises of the university committee, professors and even fellow-students. It is met with questions and answers that gives the student an opportunity to provide more clarity on the dissertation in order to convince the committee to approve it.

Stages of a Dissertation Defense

One of the most important dissertation defense tips provided by several professors is to breakdown the process into three steps:

• Preparation : This stage involves collection of all the necessary information that must be included in the defense dissertation and making all the arrangements for the actual meeting.
• The defense meeting : This is where you decide how you will present the defense. The actual meeting is hugely reliant on the performance, body language and the confidence in your oral defense.
• After the defense meeting : This stage, also known as the follow up, requires you to make the necessary revisions suggested by the university committee. You can even provide bound copies of the whole dissertation to distribute among different members of your departments. In the follow up stage, one must also think about expense that are related to publishing the Ph.D. dissertation defense as well as printing additional copies of the manuscript, if required.

How Long is a Dissertation Defense?

The first thing that a student should know is how long does a dissertation defense last? The length has to be carefully calculated to make the impact that you want. One of the most important steps in the dissertation preparation is to understand how much time each department allocates to the closing oral defense. When you plan in the early stages of your dissertation itself, you can write it in a manner that allows you to defend it in the allocated time.

Usually these meetings including the presentation, the oral defense and the question and answer session last for about two hours. In most cases, these two hours also encompass the time needed by members of the committee to deliberate.

How to Prepare for the Dissertation Defense

Now that you know how long is a dissertation defense, the next step is to prepare well enough to make your presentation impressive.

Here are some tips on how to prepare for a dissertation defense:

• Watch other students in action to learn about different presentation styles. You can attend defenses of different colleagues in your department as well as other departments in your university.
• Get all the details about the deadlines and the rules of your college or university about scheduling your defense.
• Scheduling is also a very important part of your preparation. It is important to note that members of the committee and University chairs need to make time for these defences in a very packed schedule. Coordinate the date, venue and time of your defense as early as possible.
• Prepare a manuscript adhering to the necessary formatting rules. Review your manuscript thoroughly before you hand it in. During your PH.D, your faculty will also assist you with the defense. For this, they must have a crisp and polished copy of your manuscript.
• Most colleges have the facility for a pre-defense meeting. This is the best opportunity to sort out any concerns that you may have about the actual meeting. It is a good idea to ask the chairs what types of questions may be put forward and if there are any problems with the defense that need to be resolved. When you prepare for a pre-defense meeting, think of it as the final one and give it your all.
• Put together all the material that you need for the defense. A detailed, yet to-the-point presentation must be prepared.
• The final stage of preparation is practicing your presentation over and over again. It is not just the presentation but also the approach towards the questions that you must practice.

Tips To Nail Your Actual Meeting

With these tips you will be one step closer towards a successful defense that will help your dissertation pass and be approved:

• All meetings should begin by addressing the chair. Make sure you thank all the committee members and the advisors for the efforts that they have put it. This gives you a professional start to the presentation.
• The presentation should cover the following subjects in brief:
• The research topic
• Literature review
• The methods used for analysis
• The primary findings of the research
• Recommendations of additional research on the subject in the focus.
• Do not get rattled by any discussions among the chairs. They will deliberate on any disagreements or topics of interest. This is a part of the process and is not a reflection of the presentation itself.
• There are two questions that are commonly asked that you should be prepared for. This includes the weaknesses of the dissertation and the research plans that you have made post-dissertation.
• Use subtle gestures when you are talking. Do not overuse your hands when doing so. The whole meeting including the question and answer session should have a very formal appeal.
• The tone of your voice must be assertive without making it seem like you are trying to hard. Be clear and enunciate when you speak.

Once the questions have been answered, the committee will leave the room. Then, after the deliberation, you will be informed if your dissertation has passed or not.

It’s natural to feel a mix of excitement and anxiety during this period, but with careful preparation and a positive mindset, you can navigate it successfully. In this article, iLovePhD will explore 10 tips to help you achieve viva success and make the most out of this significant moment in your academic career.

10 Tips for Viva Success

• Calm Down and Breathe: The weeks leading up to your viva can be stressful, but it’s crucial to stay calm. Find activities that help you relax, whether it’s yoga, meditation, or even a bit of video gaming. Keeping a clear head will contribute to a more focused and composed performance on the big day.
• Do Something Fun: Don’t let the time between submitting your thesis and the defense become an endless cycle of revisions. Take breaks, have fun, and reconnect with friends. Maintaining a balance between preparation and leisure will ensure you’re mentally sharp and energized when the viva arrives.
• Believe in Yourself: Remind yourself that you are the expert in your field. Despite any doubts, you’ve dedicated years to your research, making you well-equipped for the viva. Have confidence in your abilities and the knowledge you’ve acquired throughout your academic journey.
• Go in with a Good Attitude: View your examiners as colleagues genuinely interested in your work rather than adversaries. Adopting a positive attitude can alleviate unnecessary stress and help create a more collaborative atmosphere during the viva.
• Dress for Viva Success: A smart appearance not only boosts your self-esteem but also conveys your commitment to the viva process . Dressing professionally shows the examining committee that you take the defense seriously and adds to the overall positive impression.
• Read Your Thesis: Refresh your memory on the details of your research by revisiting your thesis. This is particularly important if there has been a gap between submission and the viva. A few thorough readings will ensure you are well-prepared to discuss and defend your work.
• Know the Rules: Familiarize yourself with the specific rules and procedures of your institution regarding vivas. Be aware of any presentations or additional requirements, and clarify whether you can bring a copy of your thesis into the exam and if annotations are allowed.
• Make a List of Your Own Corrections: Identify and document mistakes in your thesis before the viva. While it may be a challenging task, it demonstrates your commitment to excellence. Presenting your corrections during the viva showcases your proactive approach and may save time on post-defense revisions.
• Make Plans to Celebrate Your Viva Success: Organize or have a friend plan a celebration for after the viva. This not only provides a well-deserved break but also allows you to commemorate your achievement with those who have supported you throughout your academic journey.
• Try to Enjoy It: Embrace the moment and recognize that the viva is the culmination of your hard work. Engage in discussions with your examiners, enjoy the opportunity to share your thoughts, and appreciate the unique perspectives they bring to your research.

How to Structure Your PPT for Thesis Defense

Thesis defense presentations can vary in length. They can be 20 minutes long or two hours long. It depends on how much time is allowed for your presentation and questions.

Talk to your professor to find out how much time is set aside for your presentation. Your thesis defense presentation will be unique to your thesis. But a good presentation includes the following structure:

• Title . You need a title just as your research paper needed a title. The title slide will include the information that you’d include on your paper title. This information can include the title, your name, your school, and course name.
• Introduction . Just like most presentations, your thesis defense presentation should include an introduction slide. This slide should have the topic of your thesis and the question that your presentation answers. It should also include any objections to your research and the answer you’ll be defending in your thesis presentation.
• Literature Review . Next, create two or more slides with a review of the literature used in your research. It doesn’t need to be a complete bibliography. Although you do need to cite your sources, these slides should include your most relevant sources.
• Methodology . These slides in your thesis presentation are where you describe what method you used and an explanation of why you chose that method. If you've got some original research, include the details of that research and how you analyzed the data that you got from that research.
• Results . Some of the most important slides of your PPT for thesis defense contain the results of your research. This should include a description of the data you collected by researching and the results of your data analysis. You also should highlight what your most noteworthy finding was.
• Discussion . These slides of your PPT for thesis defense need to include your research results. Also, show how the results support your argument and how it relates to your original question.
• Conclusion . The conclusion thesis presentation slides should restate your original research questions, show the results of your research, and suggest future research and any final recommendations.
• Ending Slide . The ending slides of your thesis defense presentation are where you add an interesting fact, quote, gif, or hypothetical question. The point is to get your audience to continue to think about your topic while also grabbing their attention. You want your presentation to be memorable.

How to Make a Thesis Presentation

After you’ve seen what the structure of a thesis defense presentation is, there are some more tips that you can follow. Here are tips on how to create a thesis defense presentation:

1. Define Your Concept

After choosing which template to use, the next step is to choose the concept of your thesis defense presentation. Your concept should be relevant to your thesis. To have a fully rounded concept, try to make your presentation templates design relevant to your thesis topic.

Before working on your defense, think about the message you want to convey. This will help you choose elements such as font images and a theme that'll be cohesive.

2. Know Your Audience

Most people give their thesis defense presentation to an academic panel. This panel will look to see if you've developed a thorough understanding of your topic and thesis. They’ll also be looking to see if you've got a solid foundation for your argument.

This is why your presentation is important. You don’t want a sloppy presentation because it can give the impression of laziness and that you don’t care about your presentation. So, choose all aspects of your presentation carefully.

3. Keep Your Slides Focused   

Part of giving a good thesis presentation is to have focused slides. This means that you don’t want to have too much information on a slide. It’s best to follow the rule of one point per slide. If you've got too much on a single slide, it can be hard for the audience to follow you.

4. Structure Your Presentation

After you’ve chosen your concept, it's time to structure the content of your thesis. When structuring your information, you want to show that you understand the subject matter and that you're organized.

5. Less Is More

Each slide should have enough information that you can make your point. It’s important that your audience listens more than they read. By speaking, you show your audience that you know the topic you’re presenting on. So, when creating your slides, remember that less is more.

6. Consider Your Typography

After choosing your thesis presentation subject, consider what typography to use. Your typography should create an impact without distracting from your topic.

When considering your typography, consider your text's colors. Your text's colors should contrast with your slide's background. If the text doesn’t contrast well, it can distract the audience, causing them not to pay attention as you speak.

7. Stick to Important Data

Include data that'll strengthen your argument. Your data should also show that you’ve researched your thesis. If you can, add visuals that are relevant to your data. Visuals stimulate your brain and can increase how fast you process information. So, including relevant visuals can make your data easier to process and remember.

8. Consistency Is Key

When thinking about how to make a thesis presentation, think about consistency. For an impressive presentation, your presentation should flow well. It’s easier to have consistency when using a template because it’s already designed by a professional.

Check your finished presentation for consistency. This means making sure all your titles on slides are the same font and font size. Also, make sure that your body text is consistent throughout.

9. Explain Your Thesis

The next step in how to make a thesis presentation is to explain your thesis in great detail. The first part of this is your methodology slide . This is where you explain what method you used for your research, why you chose the topic, and how you conducted your research.

For this part of your thesis, chart and tables in your presentation are helpful in explaining data. In this section, keep your text minimal to let the chart, graphs, and data stand out. 

Next, tell the audience what the data means. Infographics are a great option to use in this section. Infographics and icons can quickly and simply show your message.

10. End Your Thesis

The last section of your thesis presentation is where you end it. Make your ending memorable to keep your audience thinking.

In your conclusion, overview your thesis topic and remind the audience of the answer that your research proved. Next, cover the important research points you want your audience to remember. A slide with icons is a great way to do this. Also, address your shortcomings in your research and how there can be improvements in future research.

Virtual Defense: Top 5 Online Thesis Defense Tips

A Master’s or Ph.D. research defense is that momentous event you have been waiting for! It is that day when you want to proudly demonstrate your passion for research to everyone who have been a part of this long journey. It’s your chance of fulfilling your dream and acquiring the degree you have worked ceaselessly for. While researchers until now were well versed with defending their thesis in person, the standstill brought by the pandemic has made us adapt newer methods to keep our work going. With advances in the technological field, it has now become easier for researchers around the globe to defend their thesis virtually.

Top 5 Tips for Effective Online Thesis Defense

Your supervisors, mentors, and colleagues are eager to hear the principle applications and significant implications of your research. Defending your thesis right from the comfort of a living room was not something researchers had ever envisioned! Several institutes have updated their procedures and examination policies to support virtual defenses. It is important that you carefully read and understand the structure, protocol, and requirements well in advance to help you plan your thesis defense skillfully. Here we present top 5 tips for effective thesis defense remotely.

1. Perfect Your Pre-Defense Preparation

• Universities and institutes have  revamped their thesis submission and defense protocols  to better suit remote requirements.
• Talk to your faculty administration department and the dissertation committee chair to decide the conferencing platform and how to structure the open research defense.
• Test your system prior to the actual defense from the same location you plan to use on D-day! Learn how to switch or share screens, control your microphones and camera, how to allow questions following your presentation, etc.
• Contact your university’s technical and IT support team for tips to enhance the technological experience.
• Share your final presentation file with the committee a few hours before the thesis defense. This way you could get to correct some typos before presenting it during the defense.

2. It is All About the Research Defense Setup

• Ensure you set up your system in a quiet and well-lit room. It is always advisable to have a light source behind your camera, or to your side.
• Remember that it’s a professional set-up. Dress formally and avoid over accessorizing.
• Sit against a plain, light-colored wall. Ensure there is no distracting artwork or bright windows in the background. You may also make use of blur-out or a subtle virtual background provided by the platform you are using. Test this in advance to check if it looks good.
• Create two rooms- a main room for public interaction and presentation, and a breakout room for private discussions with the dissertation committee or your supervisor.
• Presenting your work through a webcam is indeed different than  in-person presentation . Therefore, position your system and webcam to eye level ensuring a better face-to-face contact.
• It becomes easier to point out things on slides while presenting in person. However, it could not be done that remotely. Instead add subtle animations and highlight pointers on your slides that you want to emphasize on while defending your thesis.

3. Practice, Practice and Practice!

• Practice your talk with your colleagues, in-house mentors and supervisors. Their feedback will be instrumental in adjusting the pace of your presentation. You can also take advice from people who have previously defended their thesis using this mode. Furthermore, presenting your work to friends from other fields will help you get diverse perspectives on your work.
• Record your practice sessions to critique your presentation skills and improve based on your performance.
• Anticipate questions in advance  and prepare your answers well. Some very frequently asked questions include: 1) How does your work contribute to broader area of research? 2) Do you plan to advance your current work?
• Read recent papers published by your examiners. Remember that your examiners are leading-experts in your field of research and it is definitely a plus if you let them know how you work can relate or sync with their research goals. For instance, if one of your examiners is developing a novel technique to deliver drugs within the human body, you could suggest some ways in which your research can be aligned with theirs.

4. Begin Your Thesis Defense Early

• Reboot your system, make all the essential updates, turn off applications that might pop-up unexpectedly to ensure a smooth run. Ensure that you have a strong internet connection to support video conferencing.
• Log in to the  video conferencing software  at least 20-30 minutes in advance to ensure the technology is working fine for everyone! Talk to your attendees about how you plan to proceed with the defense.
• Request the examination committee members to login 10-15 minutes prior to your actual research defense time to check for any technical issues on both ends.
• It is recommended that you use two screens to manage your slides and video panel. In case, you cannot have a second screen, check with your committee if you can keep your camera switched off while presenting.

5. Do You Have a Plan B?

• Even the best made plans may go for a toss! Rather than panicking in the moment, it is better to have an alternative technology solution ready if something goes wrong or stops functioning mid-way through your defense.
• Discuss plan B with your supervisor/committee members, mentioning the circumstances under which you may have to implement plan B.
• Keep a backup hardware ready to use in case there are some technical glitches.

Do you remember your first reaction when you learned about having to defend your thesis online? What do you think will be the major challenges?

15 Ways to Prepare for a Successful Life Science Thesis Defense

After finally writing and editing your thesis, it’s time to defend. Here we discuss what steps you can take to prepare for your defense and provide some tips on how to successfully defend in front of the thesis committee.

For many graduate students, the thesis defense can be scary and extremely nerve-wracking, but with the proper preparation, it can actually be an enjoyable experience. It is important to remember that you are the ultimate expert in your research project. While professors on the committee may know your field of study in a general sense, they have not spent the time you have studying your thesis topic. Keep in mind that the committee is not there to make you fail, but is there to ensure you are prepared and have the skills necessary to proceed independently as a scientist. Follow the guidelines below to understand what to expect, ease your nerves and show off what you have learned over the past few years. If you need to refresh your public speaking skills, be sure to check out our articles on public speaking for the grad student and seasoned researcher .

What to expect

1. the setting..

While most defenses are open to the public, some are closed door. This will depend on the department and institution so check with your program to see what type of defense you will have.

Since many defenses are seen as more of a formality and celebration, there is often food and drinks provided. Be sure to find out if you are responsible for providing refreshments for your guests and committee in advance.

2. Inviting Friends and Family.

Most programs allow you to invite guests such as friends and family. If your family and friends do attend, tailor your presentation to a wider audience so everyone can understand. Also, don’t forget to be prepared for embarrassing questions. Take them with a sense of grace, and they will brush right over. If you’re worried that your parent with a background in life sciences may try to stump you, remind yourself that it is okay not to know the answer—just stay professional and confident.

Pro Tip: Preemptively involve your family before the time of the defense. The best way to do this is to invite them to your presentation and give them an overview prior to the defense. Ask if they have questions, and if not, provide them with intelligent questions to ask. By charging them ahead of time, they’ll be too distracted by the honor of the task to try anything else, and you’ll already be prepared to respond to their questions.

3. The Committee.

The committee is usually made up of your advisor as well as other professors from your department. Occasionally, there may be a few professors from a related department, but a majority will be from yours. The advisor serves as the moderator for the defense and does not have a say in the outcome.

4. Format of the defense.

At most institutions, the event begins with a presentation by you—sometimes with interruptions for questions. At the conclusion of your talk, the committee may have you leave the room while they decide which questions they will ask you. You will be invited back into the room for the defense portion, and the committee will ask you a series of questions. Most questions are simple and not meant to stump you, but expect a few challenging ones.

5. Failure is rare.

As stated previously, at many institutions, the thesis defense is more of a formality that happens once the final revisions have been made to your dissertation. Therefore, failure is rare. The committee does not let people defend until they are ready. Common outcomes are passing and passing with revisions required. While failure is the third possible outcome, it is unusual.

Before your Defense

6. reread your thesis..

Two weeks before you defend, set aside some time to reread through your thesis in its entirety. While it may seem like overkill since you already spent so much time writing it, going back over your thesis can help to bring the bigger picture back to mind before you present. This is very important when it comes to answering questions from the committee about the implications of your project. The details of your research will be freshly accessible in your mind after going over the paper one last time as well.

7. Pretend to be the examiner.

As you review your thesis/dissertation, try to do so from the perspective of your thesis committee. Look for the strengths and weaknesses of your research. Try to identify potential areas of confusion because the audience will likely ask questions about parts of your thesis that could have been expanded upon. Write out the questions that you come up with while rereading, and then go back and answer them to the best of your ability. Were you able to answer them thoroughly? If not, now is the time to brush up on current literature about the topic as well as the nuances of your own research study .

8. Attend other thesis defenses.

Perhaps one of the most intimidating aspects of the thesis defense is not knowing what to expect. You may have heard rumors about previous thesis defenses and how they were but if you weren’t actually there to see it, these rumors won’t be as helpful. At many universities, students are allowed to observe the thesis presentations of other students. Take advantage of this opportunity before you start preparing your presentation. Not only will this help to calm your nerves since you will have a better idea of what to expect, it will help you to form a list of dos and don’ts in your head for your own talk. Look for the strengths and weaknesses in each student’s defense and learn from their mistakes and successes.

9. Schedule a strategy meeting with your advisor.

Scheduling a time to meet with your advisor can be very helpful. Once you have outlined how your talk will go and what the points of your thesis are, share your plans with your advisor. He or she has been on defense committees in the past and can give you some insight into how you may want to alter the structure or content of your presentation based on common mistakes that other students have made. Remember that your advisor is rooting for you and was once in your shoes preparing for his or her own thesis defense.

Pro Tip: At most universities, you can meet with the committee before your defense as often as you can get them all in a room together—take advantage of this. Each time you meet with them, you will get more and more recommendations on how to make you thesis better and therefore have a better defense.

10. Get the most out of practicing.

There are a few ways you can optimize your practice time so you get the most out of it. Practice alone the first few times until you become more comfortable with your talk. When you feel like you are ready, record yourself giving your defense. One of the most convenient ways to do this is using the camera on your laptop or your cell phone. After you finish, take time to review your recording. Check out your body language and look for certain words or phrases that you use repeatedly—many of us do this when we are nervous. You can also use your recording to gauge the length of your presentation.

Once you have practiced enough, get a group of your colleagues together and practice giving your defense to them. By presenting to people with a background in your field, you have the opportunity to ask them to grill you with questions. Some of their questions may even be similar to questions the committee will ask you when it is time for your actual defense and will help you get used to answering questions about your project on the fly.

Pro Tip: In biology, there are many words that are hard to pronounce if you are not used to saying them on a regular basis. We often get accustomed to using acronyms and abbreviations in daily speech, but try to avoid this by practicing the pronunciation of any words you don’t know how to say. If you are unsure about how a word should sound, inquire with your advisor, look online for a pronunciation key, or check with your peers.

During your defense

11. don’t assume everyone has read your entire thesis..

Even though you provided the committee with your thesis in advance, it is important not to assume that they were all able to read through the whole paper. Therefore, you should present the importance of your research project, what methods you used to complete your project, and what the outcomes of your research were. You should also provide the committee with an explanation of the implications of your study both to your field specifically and also to the wider body of scientific knowledge. Stating your recommendations for future research is also encouraged because you will probably be asked about it if it is not addressed during your presentation.

On the other hand, be prepared to answer questions that may come from your paper rather than your talk. Some of your committee members will have read your entire thesis and may reference a specific paragraph or page in it when posing a question. Be sure to have a paper copy with you just in case!

12. Be prepared for questions.

There are some questions that you can anticipate being asked. For example, if there are any weaknesses or limitations to your project, you can be almost certain that your committee will ask about them. Prepare for questions like this by creating slides with graphics and text that will help you answer any questions you suspect may be brought up. You can leave a blank slide between your presentation and extra slides or save them in an entirely separate file—just be sure they are easily accessible.

Remember that you are not expected to know everything, and if you don’t know the answer, it is best to be honest. Perhaps you hadn’t thought of that question before, but you can tell the committee that you will consider it in the future.

Pro Tip: When answering questions, first listen to the entire question. Next, restate the question back to the person who posed to be sure you understood it correctly. Lastly, answer the question to the best of your ability and provide a succinct close to your answer to minimize a long dialog. If you need to pause to gather your thoughts, that is OK.

13. Dress the part.

It can be easy to put off planning what you are going to wear for your thesis defense when you are caught up in preparing for the talk itself. However, don’t put this off until the last minute. Looking professional is important in making a great impression with your thesis committee. Remember that you are defending the fact that you deserve your master’s or Ph.D. as much as you are defending your thesis—so dress the part. Your outfit should be business professional. For men, wear dress pants along with a coat and tie. Women should wear a skirt or pant suit, but a dress can work, too. Try to steer clear of sleeveless dresses, low cut tops or anything that will make you feel uncomfortable. You don’t want to have to adjust your outfit constantly during your talk; this will appear fidgety and unprofessional.

14. Be confident, but not arrogant.

Body language plays a big role in all types of communication. In your thesis defense, it is imperative to speak with confidence about your research and your findings. If you speak as though you are unsure, it will be hard for the committee to believe what you are saying and it may come off as though you aren’t confident about your results. The defense committee is there to ensure you are capable of working independently after graduation. This is your time to prove to the committee what you have learned over the past few years and that you deserve a Ph.D. in your field.

Pro Tip: Minimize your use of qualifying words such as likely, may, might, could, should, probably and usually . Excessive use of these words will cause you to lose your authority. Add strength to your presentation by instead using works like will, always and won’t .

15. Record your defense.

During or after the question section of your defense, the committee will provide you with feedback, suggestions and revisions for your thesis. However, it can be difficult to remember all of the words of wisdom when you are nervous. If you set up a video or audiotape to record your talk, you will have a record of what was discussed so you can go back and make edits to your thesis as necessary after your defense is over.

These 15 tips can help you successfully deliver a thesis defense at any university, but remember that your institution will have its own guidelines to help you prepare your defense. Since the thesis defense varies between departments and schools, it will also be beneficial to talk to your peers who have already completed one. Gather as much information as you can and jump right in to the planning stages. Don’t get caught up in your fears and remember that you are the only expert on your research. Your advisor and defense committee would not let you defend if you weren’t ready. You can do it!

Once you have submitted your dissertation, you may be asked to do a defence of your dissertation. This could be in the form of an oral presentation, a poster presentation of your findings, or you could be invited to a viva voce. Vivas, as they are usually known, are particularly common for research degrees such as MPhils or PhDs and are essentially a verbal defence of your thesis that is conducted in an interview style format. At a minimum, the viva is a way of checking you authored the thesis yourself and understand the detail, but it is also an opportunity to discuss your research findings and interpretations in depth with experts. Preparation is key for defending your thesis in a viva or a presentation format. With a bit of groundwork, you could even enjoy the discussion, after all the thesis is the culmination of all your hard work, and no one knows it better than you.

How to Start a Thesis Defense Presentation

After months and years of hard work, the moment to wrap things all up is finally here—your thesis defense presentation.

Whether you’re pursuing a master’s degree or doctorate, it’s the final step to that much-deserved achievement. 

A thesis defense requires a lot of prior research and preparation. And as important as its content is, so is how you present it because a stunning design with clear data and text hierarchy plays an immense role in comprehension.

In this article, we’ll explore how you make your thesis defense .

The organization is the key to success. Establishing some previous steps before any project or work is essential for the result to be very positive. And the defense of a thesis could not be less. 

Below, we will develop all the necessary steps to make a thesis defense presentation and we will give you some tips on how to carry them out.

How to Make an Amazing Presentation

Defining the concept of your thesis presentation, structuring your thesis defense presentation, how do you welcome the audience, tell them why you did this thesis, go into the content by explaining your thesis part by part, how to end the defense of the thesis.

After a long time of research and study, the content of your thesis is ready. Now, you have to find the best way to reflect all that effort behind your work. The information comes across more clearly if you use a visual format, as it attracts the attention of the audience. To present your thesis information in a clear, concise, and ultimately amazing way, you can use one of our unique thesis defense templates , available at Slidesgo.

As an example, in this article, we are going to use the Ecology Thesis template . With it, we will show you what to include in your presentation and how to make an attractive design.

After choosing the Google Slides and PowerPoint template that best suits the needs and subject matter of your thesis, it is time to define an overarching concept.

This is the main theme on which your designs are based. It must be relevant to your thesis as its purpose is to guide your selection of colors, typography, images, style, etc. 

These must be portrayed in a way that supports the main message of your slides and should be aligned with your concept both visually and sociologically.

Once you have defined the concept, you will have to move on to the next step: structuring the content of your thesis. A good structure will show that there is a good organization behind the work, but most importantly: it will highlight your content.

In this article, we are going to show you a structure that could be a good example of how to structure a thesis, but you can adapt it to what your specific content requires.

Before you begin your thesis defense, you should welcome your audience. A good presentation will make you connect with your audience, which will result in more general interest in your work.

Use an appropriate language register (avoid informal language), but be approachable and natural.

"Welcome to the thesis defense on [the title of your thesis]". Next, introduce yourself with your name and give a short description of your background and occupation.

Don't forget to say “thank you for attending!”

To continue establishing that connection with your audience, explain the reasons that led you to do this thesis. Tell the professional reasons, and you can even say some personal ones, which will denote closeness, and your audience will appreciate it.

Now it's time to go into the content of the thesis ! After these preliminary steps, which are just as important as the thesis itself, it is time to explain part by part the structure (which you had previously established). We are going to propose a structure for your project, but the final decision is always yours!

First impressions are very important. Because your title page is the very first thing viewers see, it must be striking and impactful. It also sets the stage for the rest of your slides.

In one glance, the following should be established:

• Thesis defense topic
• Design style

For instance, the ecology thesis’s title page uses illustrations of a natural landscape to represent the topic of nature and a striking shade of blue to set the tone.

The sans serif font used depicts clean-cut typography and style and the thesis topic is written in large and bold typography, which draws attention to it immediately.

Right after your title page, include an introduction slide to provide more details about your topic. 

This means explaining what you hope to answer with your research, its importance to your field, and why you chose it.

Continue to incorporate design elements relevant to your concept. This example has done just that by using a different natural landscape and including animals. For coherence, stick to the same typography and style throughout your presentation.

The aim of the literature review slide is to illustrate your knowledge of your thesis topic and any relevant theories.

Walls of text kill a design. For clarity, we recommend presenting this with bullet points. Each one should be short and sweet and only touch on the basics; you can elaborate on them in your speech. 

Don’t forget to be consistent with your design. In our example, we’ve maintained the tone of blue chosen and added illustrations of leaves in the far corners of the slide. 

Also, address similar research that has been done. This is to showcase your topic’s originality and, if relevant, how it’s different and/or an improvement from previously done research. 

This is one of the most important parts of a thesis defense presentation.

It allows your viewers to assess the rationality and validity of your approach and consequently, the accuracy of your results.

A great methodology slide explains the what , how, and why :

• What method did you use for your research
• Why did you choose it
• How did you conduct it

Because this part of your thesis will be rather technical, the most effective way to aid understanding is by using graphics like charts and tables. 

Keep text to a minimum to avoid drawing attention away from the graphics. If there is a text that must absolutely be included, consider using bullet points and keep them short.

Don’t forget to maintain color, style, and typography coherence.

The results slides are easily the most quantitative part of a thesis defense. 

Here, your aim is to simply introduce your findings. Select the most impactful data and highlight them here.

Just as with methodology, use graphics like charts, tables, and graphs to portray the data in a clear way. And, once again, try not to write too much text. Let the visual content do the talking .

After you’ve introduced your data, the next step would be to help your audience make sense of it. That means understanding what it means in the context of your thesis research topic and your discipline. 

Simply put, you should answer the question: What do the numbers mean?

The best way to approach this would be to do it as if you were creating an infographic . 

Illustrations like icons are a quick and simple way to represent your message. It also reduces the amount of text on your slide, which makes the information much more digestible. 

For a balanced thesis presentation, you should also address any outliers and anomalies.

To quote bestselling author Robin Sharma, “Starting strong is good. Finishing strong is epic.”

That’s exactly what to aim for in your conclusion.

Provide an overview of your thesis topic and remind your audience what you set out to answer with your research. In our example, we’ve used three icons accompanied by a short title and text. 

Following that, reiterate the important points of your research results you want your audience to take away from your thesis defense presentation. 

You can do so by expanding the next slide to have more icons and points, for example.

Don’t forget to address any shortcomings and limitations in your approach and extra points for suggesting possible improvements for future research.

We are going to give you a little tip to make your thesis defense a success. You can combine your defense with good public speaking techniques. Take a look at our article "How to become a great speaker" .

We hope this article has been of great help, have you already seen our templates to make the presentation of your thesis ? Choose the one that best suits your needs, we are sure that one of them will go perfectly with your thesis presentation! 

Good luck from Slidesgo.

IPiB Thesis Defense August 29, 2024: Gilbert Loiseau

When atoms come into close contact, they experience an attraction to each other. This attraction, called van der Waals packing, has been widely studied in large complexes of membrane proteins. Loiseau was interested in studying the effect of van der Waals forces on small systems of membrane proteins.

“Membrane proteins can be difficult to study because there are so many factors impacting the folding process,” explains Loiseau. “Understanding the strength and impacts of different atomic forces helps us to piece together how a protein folds. From there, we can better understand what goes wrong when proteins misfold in ways that lead to diseases, or potentially use membrane proteins as targets for drugs to treat diseases.”

Using a technique developed in the Senes Lab, Loiseau induced bacteria to produce small systems of membrane proteins and green fluorescent protein (GFP), which causes cells to appear green. The magnitude of the force attracting the designed proteins to each other is correlated with the intensity of GFP.  Loiseau also analyzed thousands of proteins using computer modeling to assess the strength of their attraction due to van der Waals packing.

Loiseau confirmed that van der Waals forces contribute to the attraction between proteins. However, it is unlikely to be a primary driving force for protein attraction. Future studies, he says, may want to explore the additive contribution of van der Waals forces in the presence of other forces.

“I was really able to develop and put to use so many skills in this research,” reflects Loiseau. “That’s an important part of the journey of scientific discovery. And, there’s real value in following a path that you find interesting. I’m grateful to my advisor, who helped me to find  value in learning and understanding what I was seeing. He encouraged me to keep exploring and stay resilient during the entire grad school journey.”

Loiseau also found camaraderie and developed research skills through communities in SciMed Graduate Research Scholar s, the Chemistry-Biology Interface (CBI) Training Program , and IPiB’s former DEI committee.

After graduate school, Loiseau is taking time to consider his next steps. “I’m interested in industry, in academia, but I really want to give myself a chance to see what kind of career fits best for me,” he says.

Included in Loiseau’s dissertation is a chapter he wrote to explain his research to the public . For Loiseau, the chapter was an opportunity to convey his thoughts, struggles, successes, and experiences as a graduate student. Presented as letters written between his acceptance into the IPiB program and his final research studies, Loiseau shares openly about his mental health, his experiences as a first-generation Haitian-Filipino American graduate student, and his evolving definition of success.

To learn more about Loiseau’s research, attend his Ph.D. defense, “Studying the impact of side chain packing on transmembrane helix association using computational design” on Thursday, August 29 at 12:00 p.m. CT in Room 1211 of Hector F. DeLuca Biochemical Sciences Building.

Title: Tactile Intelligence in Robotics

Date: 8/16/2024

Time: 2:00:00 PM

Location: EXP-701A

Committee Members: Prof. Lawson Wong (Advisor) Prof. Robert Platt Prof. Alireza Ramezani Prof. Taskin Padir

Abstract: In recent years, the evolution of robot electronic skin technology has introduced a novel avenue for robots to perceive their external environment and internal state. In contrast to conventional visual perception methods, tactile perception enables the discernment of additional physical properties of objects, such as friction and mass distribution, or even observes contact with higher resolution. Importantly, tactile perception is resilient to challenges posed by inadequate illumination or environmental occlusion. However, it presents inherent challenges, including a limited sensing range, compulsory physical interaction with the environment, and intricate coupling with robot control, rendering data collection and utilization challenging. Addressing these challenges and devising effective, efficient, and interpretable methods for processing tactile signals have emerged as pivotal issues in robot tactile perception.

With the development of artificial intelligence technology, we are now able to interpret tactile information from a new perspective beyond traditional sensor technology and signal processing methods, thereby expanding a wider range of robotic applications. With our continuous efforts over the past few years, we have comprehensively addressed the following challenges in enhancing robot tactile perception through the application of advanced artificial intelligence and control methods: enabling robots to explore object shapes through tactile feedback; developing tactile-based safety mechanisms for human-robot collaboration; enhancing the locomotion adaptability of snake robots on irregular terrains through tactile perception; utilizing whole-body exteroceptors and proprioceptors for accurate body schema estimation; and implementing tactile gesture recognition in human-robot interactions. At the same time, we developed a modular full-body electronic skin system for robots and its accompanying software, which can accurately detect forces applied to the robot’s entire body and perform high-speed tracking of the real-time kinematics of the robot’s sensor array.

In conclusion, this dissertation explores how robot tactile perception can accomplish complex tasks in various scenarios or achieve performance improvements in traditional tasks through the integration of sensor technology, machine learning, control theory, and robotics. Through extensive theoretical and experimental analysis, we have demonstrated the critical role of tactile perception in embodied intelligence for robots and established a fundamental knowledge framework for future academic research in this field.

Milkweeds, monarchs, and their microbes: understanding how plant species influences community composition and functional potential

Plant secondary metabolites (PSMs) are specialized compounds produced in response to a range of insect herbivores and microbes, making them important in shaping tri-trophic interactions. However, despite being well-studied in the context of plant-insect coevolution, it is unclear how PSMs impact microbial communities associated with plants and the insect herbivores that feed on them. The overarching goal of this dissertation was to better understand how variation in plant defensive responses, particularly expression of PSMs, influences the composition and functional potential of microbial communities associated with plant tissues (roots and leaves) and insect herbivores. Monarchs ( Danaus plexippus ) and their milkweed hosts ( Asclepias spp.) are well-studied for mechanisms of plant defense and insect counter defense, but little is known about the role of associated microbial communities in this iconic system. To address this knowledge gap, a combination of metabarcoding and metagenomics was used to characterize the taxonomic composition and functional gene profiles of bacterial communities associated with plant tissues (i.e., phyllosphere and rhizosphere) and monarch caterpillars fed on multiple milkweed species ( A. curassavica , A. syriaca , and A. tuberosa ). Findings show the composition of phyllosphere, rhizosphere, and monarch microbiomes vary across milkweed species in terms of diversity and relative abundance of bacterial taxa. Furthermore, phyllosphere and rhizosphere microbiomes were shown to have distinct functional gene profiles and presence of potential PSM metabolism genes that also varied across milkweed species. Rhizosphere microbiomes had a greater overall capacity for PSM metabolism compared to the phyllosphere, having more genes, and associated metabolic pathways involved in degradation or detoxification of known classes of PSMs. However, plant associated microbiomes were not generally affected by monarch feeding, evidenced by few changes in taxonomic composition or abundance of genes predicted to be involved in PSM metabolism. Interestingly, monarch microbiomes shared >90% of their taxa with their host plants, but there was little evidence of PSM metabolism genes present in functional gene profiles. Overall, this dissertation lays the foundation for understanding how PSMs shape all the microbial communities associated with monarchs and their milkweed hosts. Findings suggest plant defensive responses affect the assembly, functional potential and ultimately the evolution of plant and insect microbiomes.
