Randy Wang

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 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. As of December of 2005, I have joined Microsoft Research India to pursue this project full-time. Although the Microsoft lab is based in Bangalore, these days, I mostly live and work in Lucknow, UP, India.

Recent projects:
o Distance learning for primary education in rural India (The Digital StudyHall: Postmanet, EdTV, and the Learning eBay)
o Distributed mobile storage
