Professor of Political Behavior

Sciences Po Paris


I'm a Professor of Political Behavior at the CEVIPOF in Sciences Po Paris. Prior to my current position, I worked at the University of Montreal and King's College London.  Before that, I completed all my studies, including PhD, at my local university in Belgium, the University of Louvain.

I use (quasi) experimental methods to study elections and democracy. My research complements traditional voting behavior studies by examining the role of elections in shaping people's experience with representative democracy. Additionally, I occasionally contribute to methodological discussions in social sciences, particularly regarding surveys and experiments. I'm a political scientist by training but I frequently collaborate with economists trying to bridge the two disciplines. Political scientists would say that I'm a rational choice analyst, but economists would say that I'm behaviorist.

I have published a slate of articles on these topics (see here). Below is a selection of my favorite articles that best represent my current research interests.
