I am an Associate Professor at the University of Notre Dame’s Keough School of Global Affairs. I study democratic policymaking and public opinion with a focus on managing immigration, ethnic tensions, and other demographic issues. I specialize in computational and experimental methods, drawing on diverse data sources from surveys to historical records. My book In Our Interest: How Democracies Can Make Immigration Popular (Columbia University Press, 2025) examines under what conditions most people accept freer immigration despite their biases.
My research has been published in American Political Science Review, Journal of Politics, Perspectives on Politics, and World Politics. It has been recognized by leading grants and awards, including from the Russell Sage Foundation and Department of Defense Army Research Office. I have also written for The Atlantic, The Washington Post, and Foreign Affairs, and been featured in The New York Times, Economist, and Financial Times, as well as by think tanks such as the Bipartisan Policy Center, Center for Global Development, and Niskanen Center.
Currently, I am the author of the Popular by Design newsletter and a contributor at Good Authority, and an Associate Editor at the Journal of Ethnic and Migration Studies. Prior to my appointment at Notre Dame, I was an Assistant Professor at the University of North Carolina and a Postdoctoral Associate in the Jackson School of Global Affairs at Yale University. I received my joint Ph.D. in Politics and Social Policy from Princeton University.
