About Me

I am an assistant professor in the department of Government and Politics at the University of Maryland, College Park.

My research interests include American political behavior, political psychology, partisan and social identity, and polarization. Specifically, my work focuses on the polarizing effect of partisan sorting, and the consequences of sorting for political behavior in general.

Some of my research has appeared in journals such as American Political Science Review and American Journal of Political Science.

I am currently finishing a book manuscript on partisan sorting and polarization in American politics.
