I'm a Professor in the Computer Science Department at the Ecole Polytechnique (DIX), 3A Director, Director of the AI Trust Chair, X Crédit Agricole Director, Director of the AI and Optimization for Mobility X-SNCF Chair and Scientific Director for industrial relations in the Computer Science Department and Laboratory at the Ecole Polytechnique (DIX and LIX).

My research focuses on the development of decision support tools for complex industrial problems, Artificial Intelligence (AI), Operations Research (OR), Network Optimization, hybrid approaches between AI and OR for future ethical, sustainable and trusted AI systems.

I am in charge of the GdT OR (Optimisation des Réseaux) working group and the REST (Réseaux Energie Services et Transports ) research axis of the GDROD of the CNRS and a member of the GDROD scientific council of the CNRS.
