Hello! I’m an Assistant Professor at Stanford in the Department of Management Science & Engineering (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. I’ve recently been looking at police discrimination, stop-and-frisk, swing voting, voter fraud, filter bubbles, privacy legislation, 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). Before joining the Stanford faculty, I worked at Microsoft Research in New York City.
