I received my B.Tech from IIT Bombay in 2001, and my PhD from Stanford in 2006. I spent the next 6 years (2006-2012) in the Microeconomics and Social Sciences group at Yahoo! Research. In August 2012, I moved to Cornell as an Associate Professor of Information Science in the School of Computing and Information Science. I received tenure in June 2016.

Update (June 2019): It is time to move on, to explore new directions. I have resigned my position at Cornell, and will no longer be pursuing or undertaking any activities (conference chairing, talks, program committee service, grant reviewing, book writing, or anything else!) related to my research and career thus far.
More when I am ready. And in the meantime, to all those I have met along the way over these past several years, I wish you all the best!

About my academic work:

My research focused on using mathematical analysis to inform the design of online systems. I was interested especially in the analysis and design of online user contribution economies---both explicit, as in crowdsourcing and user-generated content platforms, or implicit, as in the collection of data from privacy-aware users---within a mathematical framework, with a focus on incentive design. I also got rather curious about the idea of `behavioral' mechanism design, exploring how departures from the classical economic models of agent behavior can impact optimal design.
(Then, of course, I stopped being curious about these things, as you've probably inferred from the update above. Go figure!)
