Welcome!

I am a political scientist studying political attitudes and behavior using experimental, spatial, and computational methods. My research examines how shifting socio-economic and political contexts shape the stability of mass attitudes and behavioral outcomes such as voting. I use fine-grained geo-localized data, survey experiments, and computational text and image analysis to investigate these questions. My work has been published or is forthcoming in the American Journal of Political Science, Comparative Political Studies, and West European Politics.

Currently, I work as a Junior Lecturer (postdoc) at IDHEAP, University of Lausanne. Together with Pirmin Bundi and Frédéric Varone, we study political intolerance among citizens and elites as part of the ERC-funded POLPOP project on how politicians evaluate public opinion. Between 2023 and 2025, I was a Max Weber Fellow at the Department of Political and Social Sciences, European University Institute. I have experience teaching quantitative methods, survey experiments, and computational methods at both undergraduate and PhD levels. I defended my dissertation with no corrections at the Department of Politics and International Studies, University of Cambridge, in November 2023.

During the 2025/2026 academic year, I am organizing the IDHEAP-LAGAPE seminar series at the University of Lausanne
