Welcome!

I am a political scientist with interests in political attitudes and behaviour, as well as experimental, spatial, and computational methods. My research examines how changing social, political, and economic contexts and political elites affect mass attitudes and behavioural outcomes such as voting. To study these phenomena, I leverage fine-grained geo-localised data, survey experiments, and automated text and image analysis. I have experience teaching quantitative methods, survey experiments, and computational methods at both undergraduate and PhD levels. 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 collect data on Swiss citizens and politicians as part of the ERC-funded POLEVPOP 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 defended my dissertation with no corrections at the Department of Politics and International Studies, University of Cambridge, in November 2023.
