Matt Grossmann is Director of the Institute for Public Policy and Social Research and Professor of Political Science at Michigan State University. At Niskanen, he is the host of the Science of Politics podcast (designed to summarize research for political professionals) and contributing to work on the future of partisan polarization and national policymaking.

His current work explores the mechanisms of economic inequalities in policy influence and the policy consequences of Republican gains in the states. Grossmann has also worked in practical politics at the local, state, and national levels (and abroad) in political campaigns, parties, interest groups, and government. The research institute he directs includes a large survey lab, a policy research database, a state government outreach and legislative training program, and a candidate recruitment and leadership program.
