I am a postdoctoral lecturer and researcher at the Political Science Department of the University of Lucerne, located in the heart of Switzerland. I specialize in the comparative analysis of migration-related politics and policies, and how the resulting boundaries shape hierarchies in rights and citizenship within and across states. In short, my work focuses on analyzing lines that divide. The empirical puzzles related to this theme often come with crucial normative implications and ethical dilemmas. This is why I also try to speak to political theory and philosophy on boundary making from an empirical perspective.
