Présentation

I am a researcher in operations research and optimization. I obtained my PhD from ISAE-Supaéro (Toulouse), where I worked on the unsplittable flow problem with applications to satellite communication networks. I then held several postdoctoral positions at CIRRELT (Montreal), LAAS-CNRS (Toulouse), and LIMOS (Clermont-Ferrand).

My research mainly focuses on mixed-integer linear programming, combinatorial optimization, with applications to networks, transportation, and sustainable systems. I am particularly interested in decomposition methods, polyhedral approaches, and the use of concepts from cooperative game theory such as the Shapley value. More broadly, I aim to connect optimization methods with societal and environmental challenges.

Here is my Google Scholar.
