I am Director of Data Science at the Program for Opinion Research and Election Studies at the University of Pennsylvania. My research focuses on the ways that political geography, the economy, and social arrangements influence electoral coalitions and public opinion. Methodologically, I develop new methods to get more out of public opinion data.
At Penn, I teach classes on survey research methods and data science. I also work with the NBC News Decision Desk as an elections analyst.
My research has been published in the American Political Science Review, the Journal of Politics, Political Science Research and Methods, and Political Analysis. My work has been covered in the New York Times, the Washington Post, the Economist, and other news outlets.
Previously, I was a postdoctoral fellow at Princeton’s Center for the Study of Democratic Politics. I received my Ph.D. in political science from Stanford University and my undergraduate degree from the University of Pennsylvania.
