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. In addition to mixed-method studies, my lab works on experimental social systems, such as Link Different and piggyback prototypes. I spend a lot of time writing papers; many thanks to Yahoo! (RIP Labs), Google, Facebook, Samsung, Yik Yak, the NSF, ARL & DARPA for letting me do that. Over the years, my students and I have been fortunate to win a number of best paper awards and honorable mentions from ACM'S SIGCHI.
Recently, I served as one of the program co-chairs for ICWSM 2016, and was awarded an NSF CAREER (thx + yay!). I'm also a Teach For America alum (Chicago, 2002–2004). I primarily hang out these days over on Twitter and IRC. You can send me email at my work address.
