Welcome! 

I am an Assistant Professor at the Centre for Political Research (CEVIPOF) and the Department of Political Science at Sciences Po , Paris. Until September 2026, I am also the Alfred Landecker Postdoctoral Fellow at the Blavatnik School of Government, University of Oxford.

My research interests lie at the intersection of international normative political theory and theories of citizenship, where I work primarily on questions of cosmopolitanism and political motivation, the ethics of immigration and citizenship policy, and nationalism. I am currently working on a monograph, provisionally entitled Granting Citizenship, which explores the political ethics of external citizenship policies and brings together divergent literatures on global and historical injustice, the moral limits of markets, and the ethics of war.
