Jeffery A. Jenkins holds appointments as professor of public policy, political science, and law at the USC Gould School of Law and Provost Professor of Political Science, Public Policy, and Law, Judith & John Bedrosian Chair of Governance and the Public Enterprise, Director of the Bedrosian Center, and Director of the Political Institutions and Political Economy (PIPE) Collaborative at the USC Sol Price School of Public Policy. He previously held tenure-stream positions at the University of Virginia, Northwestern University, and Michigan State University.

His research interests include American political institutions and development (with a special emphasis on Congress and political parties), lawmaking, separation-of-powers, and political economy. Much of his work takes a positive political theory (or rational choice) approach, and examines how political actors pursue their interests while being constrained by formal and informal institutional arrangements. His current work involves papers on the ideological content of federal lawmaking in the post-war era and book projects on how civil rights policy has been dealt with in Congress over time and how the Republican Party evolved in the South after the Civil War.

Jenkins holds a PhD in political science from the University of Illinois at Urbana-Champaign and an MS in mathematical methods for the social sciences from Northwestern University. He has been a postdoctoral fellow at Princeton University and Michigan State University.

He currently serves as the editor-in-chief of The Journal of Politics.
