 I'm not one of those people that has a mindset of this is exactly what I want to do. I decided for my master's degree I'll just head straight into computer science even though I was studying biochemistry. I was hanging out at my friend's house and he's just on his computer playing a game. I was thinking, why are you playing such a simple game? It turned out he was building that game for his course. One of my favorite books is Alice in Wonderland and that's because she does these crazy things and in a way I think that's quite similar to the project I'm working on right now. I'm exploring time reversal waves and ultramagnetic waves and I want to make that wave go backwards so hopefully eventually we can use it as a cancer treatment. Basically the advice in general is don't restrict yourself just one step at a time. I'm Crystal and I am a PhD student studying computer science.
