I am an Associate Professor of Information Science in the School of Computing and Information Science at Cornell University. I received my B.Tech from IIT Bombay in 2001, and my PhD from Stanford in 2006. Prior to joining Cornell, I spent 6 years (2006-2012) in the Microeconomics and Social Sciences group at Yahoo! Research. My research centers around economic behavior on the Internet. I am currently most interested in the economics of online user contribution---whether explicit contribution, as in online crowdsourcing and user-generated content systems, or implicit, as in the collection of data from privacy-aware users---with a particular focus towards using formal game-theoretic analyses to inform the design of these systems. Most recently, I have begun to explore the idea of `behavioral. mechanism design---using increasingly accurate models of agent behavior derived from experimental and empirical studies---to design incentives for these environments.
