Short Biography

I am researher at LIX (Laboratoire d’Informatique de l’Ecole Polytechnique), member of the OptimiX team and associate professor at Paris1 Panthéon-Sorbonne University. My research focuses on operations research, mathematical programming, network optimization and the development of decision support tools for complex industrial problems. My current research projects concern the development of new algorithmic tools, combining mathematical programming, linear and non-linear optimization, constraints programming and learning to solve challenging problems related to: Trusted and responsible AI, energy saving in multi-hop wireless networks, cybersecurity in telecommunication networks, urban air mobility or banking data analysis. I am responsible for the industrial collaborations at the Department and Laboratory of Computer Science of École Polytechnique (DIX and LIX). I am a member of the scientific council of the GDRRO (OR research group of the CNRS), of the Research axes REST (Réseaux, Energie, Service et Transport) and head of the GdT OR (Groupe de Travail Optimisation des Réseaux) of the GDR RO.
