Hello! I'm an assistant professor in politics at Princeton. I develop quantitative models and methods for new forms of social science data. These new sources include many forms of data previously thought to be too unstructured to study: audiovisual data conveying human emotion, path data for sequential decision-making, and mobile location data on movement and social interaction. My research touches on political communication and ethnic politics, including racialized policing in the United States and Sunni-Shia relations in the Middle East.
My research has appeared or is forthcoming in Science, the Journal of the American Statistical Association, the Proceedings of the National Academy of Sciences, and the American Political Science Review. It received the John T. Williams dissertation prize and the best poster award by the Society for Political Methodology, and it has been supported by a NSF Graduate Research Fellowship.
