Howdy!My research is generally in the areas of web-scale information management, distributed data-intensive systems, and social computing. Most recently, I've been working on (i) spam and crowdturfing threats to social media and web systems; and (ii) geo-social systems that leverage large-scale spatio-temporal footprints in social media.
Congrats to all of our Coding Gig participants and winners!
