Ph.D. Candidate
Department of Government
Harvard University

Hi there! I am a PhD candidate in the Department of Government at Harvard University. My research is broadly situated at the intersection of political behavior, comparative political economy, and applied statistics. Specifically, I study the underlying causal drivers of increasing fragmentation in European societies, with a special focus on immigration, xenophobia and inequality. Methodologically, I specialize in quasi-experimental research designs to draw causal inferences from observational data.

At Harvard, I am affiliated with the Institute for Quantitative Social Science, the Weatherhead Center for International Affairs, and the Minda de Gunzburg Center for European Studies. I am also affiliated with the Transformations of Democracy research group at the WZB Berlin Social Science Center. I hold masters degrees in Statistics (2020) and International Relations (2017).

In autumn 2022, I will join Nuffield College at the University of Oxford as a Postdoctoral Prize Research Fellow.
