Hi. I’m a Senior Researcher at Microsoft Research in New York City, and in the fall I’ll be joining the Management Science & Engineering Department at Stanford. I work in the area of computational social science, an emerging discipline at the intersection of computer science, statistics, and the social sciences. I’m particularly interested in applying modern computational and statistical techniques to study social and political policies. For example, I've recently been looking at stop-and-frisk, swing voting, filter bubbles, do-not-track, and media bias. I intermittently blog at Messy Matters. Before joining Microsoft Research, I studied at the University of Chicago (B.S. in mathematics) and at Cornell (M.S. in computer science; Ph.D. in applied mathematics), and worked at Yahoo Labs. If you would like to get in touch, please send me an email.
