Previously, he has held posts at Washington State University, Princeton University, and the University of Utah. Luedtke’s research explains how political and economic factors affect immigrant rights and freedoms, particularly as policy regulation shifts between different levels of authority (ranging from global to local). He demonstrates how political institutions mediate public xenophobia and how public opinion interacts with the political economy to shape parties’ incentives on immigration. Luedtke’s work has appeared in the British Journal of Political Science, State Politics & Policy Quarterly, Governance, European Politics, and the Policy Studies Journal. He served as a Europe adviser for Freedom in the World.
