I am a former student of the École Normale Supérieure (Paris, rue d’Ulm). In 1992, I earned my PhD in theoretical physics from the University of Paris VI, with a thesis entitled “Random Walks in Random Media.” Following my doctoral work, I focused on disordered systems and their statistical and physical properties. Since 1992, I have held a permanent research position at the CEA. I am currently Research Director at the Institute of Theoretical Physics (IPhT) in Saclay, a member of the Centre d’Analyse et de Mathématique Sociales (CAMS) at the École des Hautes Études en Sciences Sociales (EHESS), and, since 2026, an external faculty member at the Complexity Science Hub (Vienna).

​

My research interests have progressively expanded toward applications of statistical physics to complex systems, complex networks, theoretical epidemiology, and spatial networks. Combining data analysis and modeling within the framework of statistical physics, I also work on various aspects of the emerging science of cities. To date, I have authored over 200 scientific publications, as well as several books on complex and spatial networks and urban systems. In 2024, I was awarded the Jean Ricard Grand Prize of the French Physical Society.
