Prospective Caltech/MIT students: what are you doing research on?

This is a question for those students trying to get into Caltech and MIT who say they’re doing or have done some large amount of research on a particular thing. What exactly are you researching and what are you attaining from your research? I’m not being skeptical or anything, I’m seriously interested in doing some sort of research, but I’m not exactly sure how to approach it.

<p>um, anyone???</p>
