Welcome! I’m an Assistant Professor at Stanford in the Management Science & Engineering Department (in the School of Engineering). I also have courtesy appointments in Sociology and Computer Science. My primary area of research is 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 and design public policy. For example, I’ve recently been looking at stop-and-frisk, swing voting, filter bubbles, do-not-track, and media bias.
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 was a postdoc in the Stanford math department. Before joining the Stanford faculty, I was a Senior Researcher at Microsoft Research in New York City.
