This page is out-of-date. The latest.

I received my Ph.D. from the University of California at Berkeley. I was an assistant professor in the Computer Science Department at Princeton University, before Princeton and I mutually decided we had had enough of each other. I'm currently working on the Digital StudyHall (DSH) project, a project that we started while at Princeton that seeks to improve children's education for the rural poor and the urban slums in India. These days, I mostly live and work in Lucknow, UP, India.

(I have been told by the Princeton CS department that they continue to receive grad school applications from students who express desire to work with me. To such applicants, please note that I don't work at Princeton any more: if you wish to be accepted by Princeton, you should refer to other faculty there in your application; if you are interested in DSH, you should email me directly.)
