I'm a recent physics grad from Texas A&M and will be starting graduate school at UC Berkeley in the fall. I have been participating in distributed computing projects for many years. SETI@HOME for the majority of my time, and then while waiting for my invitation for this project I did a little climateprediction.net work. I am happy to help out with scientific research, but I think the primary reason for my participation is that I enjoy "getting something done" while I am physically doing nothing :)
