I am a Research Scientist at Médialab, Sciences Po, and a Fellow of CRI/LPI of the Universite of Paris. I am a Computational Social Scientist working at the intersection of mathematics, computer science, sociology, and political sciences.
Previously, I was at the Centre for European Studies and Compared Politics (CEE) at Sciences Po. Before that, I was at the Computer Science Department of Sorbonne Université (LIP6), with the Complex Networks Team. Before that, I was a Doctoral Fellow at the Centre de Mathématiques Appliquées (CMAP) at École Polytechnique, Université Paris-Saclay.
