I am a Postdoctoral Fellow at the Digital Society Project. Starting Fall 2025, I will be a Visiting Assistant Professor in the Politics and Public Affairs Department at Denison University. I am a political scientist comparatively studying authoritarian politics, with a substantive focus on affective polarization and democratic backsliding, and a methodological focus on computational and experimental analyses. My research and/or writing has appeared in diverse outlets, including The Washington Post and peer-reviewed Democratization, Computation, and Ethnopolitics. More information on my background and research can be found on my website and on my Google Scholar profile.

I am Distinguished Professor at the Department of Political Science at UC Davis. I have published in the American Political Science Review, the American Journal of Political Science, and the Journal of Politics. I am the author of A Unified Theory of Party Competition (Cambridge Press, 2005; co-authored with Samuel Merrill, III, and Bernard Grofman), and of American Affective Polarization in Comparative Perspective (2020, with Noam Gidron and Will Horne), part of the CUP Elements Series in American Politics.
