Seth Jolly is an Associate Professor of Political Science and Director of Graduate Studies at the Maxwell School of Syracuse University. His research focuses on European regionalist movements, political parties, ideology, and the European Union. His 2015 book, European Union and the Rise of Regionalist Parties, investigates whether European integration increases regionalist, or sub-state nationalist, mobilization within European Union member states. This project explores the strategies and electoral success of regionalist political parties in Western Europe, arguing that deeper European political and economic integration increases support for sub-state nationalist parties because it increases the viability of independent small states within the European Union. He is also one of the co-Principle Investigators of the Chapel Hill Expert Survey (CHES), an expert survey designed to evaluate political party ideologies.
