I’m thrilled to announce that I have completed my PhD thesis defense! It’s been a long and challenging journey, but I’m proud of all the hard work and dedication that I’ve put into this moment.

Although I am not an easily stressed person, I thought it would be interesting to capture the intensity of my experience during the defense. To do so, I wore an electrocardiogram during the entire event. In the plot below, the data is presented with arrows indicating the various moments. During the presentation part, my heart rate remained high but relatively stable. As I answered questions from the committee, my heart rate fluctuated, reflecting the varying levels of stress and anxiety that I experienced.

This plot does not reflect any meaningful data and only grossly reflects the physical response of my body, I did find it interesting to see all the bumps directly correlated with the various questions. While these bumps could be stress-induced, they may also only reflect the act of speaking with hand movements increasing the necessary blood flow. I enjoyed gathering the extra data, and now I see this plot as a reminder of my success and my ability to overcome challenges in the future. If you’re interested in using the data, is it freely available here (HR) and here (ECG).

I’m incredibly grateful to my advisors, committee members, friends, and family for their unwavering support throughout this process. Their encouragement and guidance have been invaluable, and I couldn’t have done this without them. Once again, I’m proud to have completed my PhD thesis defense and excited to see where this accomplishment takes me in my future professional endeavors.
