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.

Research interests:

  • Social media: social media and news diets, algorithmic biases, polarization, socio-technical fragmentations and echo chambers, misinformation and other disorders/dysfunctions.
  • Computer Science: Recomender Systems and evaluations, AI explainability, machine social cognition, diversity and information-theoretic metrics, Heterogeneous Information Networks, social network analysis, graph embedding methods.
  • Political Sciences: social movements, cleavages, dimensionality, emerging tensions, populism, political attitudes, polarization and issue alignment, ideological scaling.
