Yep, I'm nerdy, but I'm aware of it, so I think I do a pretty good job of keeping it in check. If I'm not doing research (trying to finish up my PhD) or teaching (I lead a series of workshops geared towards learning the math and sciences in a collaborative environment), then I'm probably biking with my friends to sample some LA cuisine. Or I could be playing the occasional video game.
I recently forced myself to take the Myer's-Briggs test. Apparently I'm an INTJ. Whatever that means.
