Welcome!

I study mass politics through political science, communication, psychology, and history with a wide range of social science methods.

I’ve written 3 books, 2 dozen articles, & many public essays on contentious politics and democratization, with particular focus on partisanship, violence, identity, ideology, & messaging to inform national discussions.

I’m executive director of the Center for Communication & Civic Renewal at the University of Wisconsin-Madison, and I consult for researchers and groups advancing democratic rights & representation.
