I am a student at the University of Washington. I dilly dally in a few fields - Math, Chemistry, Physics, Computer Science - and am trying to find my way into a graduate school in one of these fields. I'm currently working in a theoretical chemistry group, so I spend a lot of my time on the physics and stack overflow sites. The link under 'website' is our group's site - I'm the dude in the middle.
