Most of my work focuses on (affective) polarization, political information processing, and political ideology and identities. I am particularly interested in the interplay between information environments and these variables. In my research, I rely on a variety of quantitative methods, including survey, field, and natural experiments, as well as survey and geospatial data. I’m also the director of the Democracy and Information Group, where we explore these and related issues.
Before joining the University of Pennsylvania, I was faculty at the Amsterdam School of Communication. I received my Ph.D. from Stanford University. My research has appeared or is forthcoming in various journals across disciplines, including the American Journal of Political Science, PNAS, the Journal of Politics, the British Journal of Political Science, Public Opinion Quarterly, Journal of Experimental Political Science, Political Psychology, the Journal of Personality and Social Psychology, and the Journal of Experimental Social Psychology.
