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 the 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.

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 to understand 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. 

10. Sleep

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.
