Welcome!
I am a Postdoctoral Research Fellow at the Institute for Advanced Study in Toulouse (IAST), Toulouse School of Economics (TSE). In September 2024, I completed my PhD in Political Science as part of DYNAMICS (Humboldt-Universität zu Berlin). During my PhD, I was a visiting researcher at The Mamdouha S. Bobst Center for Peace and Justice and the Department of Politics at Princeton University. I am also involved in The Humboldt Governance Lab (Humboldt GovLab).
My research focuses on the political economy of crime and discrimination. In particular, I investigate (1) how judicial reforms affect hate crimes, (2) how the police strategically report on crime, and (3) how policies targeting marginalized groups are used for political gain. My side projects include work on parties, social norms, and protest. Some of my work has been published or accepted for publication in Electoral Studies and The Journal of Politics. Methodologically, I specialize in causal identification and computational social science, combining field, natural, and survey experiments, with recent advancements in Natural Language Processing.
On this website, you can learn more about my research and teaching profile, and download my CV. Feel free to reach out if you are interested in my research and would like to chat 
When not buried in papers and datasets, I’m probably hunting for records. Always happy to share concert tips, obscure vinyl recommendations, or obsess over how live music is the best form of human connection.
