I'm broadly interested in social computing (the social uses of the internet), and probably most of what you want to know is over on the comp.social lab site. I spend a lot of time writing papers; many thanks to Yahoo!, Google, Facebook, Samsung, the NSF & DARPA for letting me do that. My lab also likes building experimental web systems, such as Link Different. Recently, I became a DERP fellow. Tech's press office is fantastic, and sometimes folks in the press write about my work. I'm usually on the hunt for a small number (n ∈ [0, 1]) of exceptional PhD students.
