FNSP Professor of Political Behavior

Sciences Po Paris


I'm a FNSP Professor of Political Behavior at the Center for Political Research (CEVIPOF) in Sciences Po Paris. Prior to my current position, I worked at the University of Montreal and King's College London where I directed the Quantitative Political Economy Group during 5 years.  Before that, I completed my studies, including PhD, at my local university in Belgium, the University of Louvain.

My areas of expertise include democratic institutions, elections, political participation, and voting, which I approach from a micro perspective. More specifically, I use (quasi) experiments to study the role of elections in shaping people's experiences with representative democracy. I also occasionally contribute to methodological discussions in the social sciences, particularly regarding surveys and experiments.

I've also conducted a dozen of large-scale experiments and surveys in various countries, including Belgium, Canada, France, Germany, and the United Kingdom. In 2020, I've coordinated the European Political Institution Survey, in which more than 15,000 respondents participated across 15 European countries.
