I am a research fellow at the Simons Institute at the University of California, Berkeley. I recently got my Ph.D. from the department of computer science at Princeton University. My main research interests are algorithms for massive data (or in more fashionable language, "big data").

Before coming to Princeton, I studied computer science and math (courses 6 and 18) at MIT.
