I am a Provost Professor of Public Policy, Political Science, 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 Sol Price School of Public PolicyUniversity of Southern California.

American political history is a favorite topic of mine and plays an important role in my research.  Much of my work focuses on the origins and development of American political institutions, notably congressional and partisan institutions.  I also use historical data to test contemporary theories of legislative organization and behavior.

I have been Editor in Chief of The Journal of Politics since January 2015.  For more information on the journal, and background on the team approach that I employ, see here.
