I am an Assistant Professor of Politics and Public Affairs at Princeton University. I study bureaucratic politics and political behavior, and devote particular focus to law enforcement agencies. In addition to evaluating the efficacy of police reform, I also study how police tactics influence public perceptions of institutions and the social world.
I have also authored studies on partisan polarization, political communication and racial and ethnic politics. I conduct methodological research on issues relevant to my substantive work, including statistical modeling and experimental design. My work exploits a range of research designs and data sources including survey and natural experiments, qualitative interviews and administrative records obtained through public information requests to government agencies.
My research has appeared or is forthcoming in American Political Science Review, The Journal of Politics, Proceedings of the National Academy of Sciences, Quarterly Journal of Political Science and Political Analysis, among other peer-reviewed journals. I received a B.A. from New York University and a Ph.D. from Stanford University. Before beginning my doctoral studies, I was a staff writer at The Washington Post, where I covered crime and politics in the Washington, D.C. region.
