My dissertation defense was on Tuesday … and … I passed!
(It’s taken me a few days to sit down and blog about it, because my parents are visiting and Family Time is fun but exhausting.)
It was not surprising to pass—it’s extremely unusual in any PhD program for someone to fail after being allowed to defend—but I am so very happy and relieved to feel like I deserved it. That was my greatest fear over the last year: that I would be passed out of kindness or pity or just to get me out of there. I am comfortable that that’s not what happened.
Defenses in my department are a short (30-minute) public talk, followed by an hour or two of private questioning by the committee. My extreme social anxiety doesn’t transfer into prepared public speaking situations; as long as I’ve practiced (which I definitely did here), it only takes a few sentences for me to get comfortable. So that part went quite well.
The questions from my committee were generally relevant and reasonable. It was all big-picture knowledge stuff, plus some questions about possible follow-up work. No one asked me to justify any of my methodology or even any of my conclusions. I had to write on the board a few times, but didn’t need to pull up any plots or refer to anything specific in my written dissertation.
My answers were awkward and clunky at times. Someone once told me that the point of a PhD defense is to find out the limits of your knowledge (and decide if it’s enough)—and so to expect people to keep asking questions until they ran into those limits. I think not all of the clunky answers were my fault, though. Some of my committee members were just not very good at articulating what they were looking for, and it took a few rounds of clarification to get there.
There was only one point when I felt really nervous, and that was when they sent me out of the room after an hour of questions, to decide if they were done or if they needed to ask me more. I began the wait feeling confident, but after about five minutes started to worry that it was taking too long, even though rationally I knew that it wasn’t. (And it wasn’t: they called me in after about ten minutes to congratulate me and sign the passing paperwork.)
I passed with no revisions, meaning that I don’t have to rewrite anything or add components to my dissertation. Each committee member pointed out a few typos and suggested a clarifying sentence here or there in my introduction, but that’s all. This is fairly common in my department, nothing extraordinary, but it still feels good.
Officially, I will receive my PhD in mid-August, when my university confers degrees that were completed during the summer semester. I do still have to fix those typos and formally submit my dissertation to the university. (Submissions are electronic these days, with much less stringent margin and formatting requirements than they used to require for paper copies.) I’m also waiting to hear back from the referee on my latest paper, and I won’t feel mentally totally done until I’ve taken care of revisions on that.
To be honest, it still feels pretty unreal. Did this actually happen? Am I actually (almost) done? My brain doesn’t quite know what to do with it, I think. But it does feel good.
