About Me
I am a tenured research associate (Chargé de Recherche) at the Inria centre at the University of Lille, in the INOCS team. My research is rooted in stochastic and mixed-integer programming, in both their theoretical and computational aspects. I increasingly work at their interface with data science. The question behind most of my work is how to keep large, data-driven optimization models tractable without losing optimality guarantees. I take inspiration from industrial planning and scheduling problems, especially in energy systems. I am open to collaborations on any topic at this interface, including machine learning approaches.
I studied Mathematical Engineering at UCLouvain, where I received my Master’s degree in 2019. I then received my PhD from Universität Trier, supervised by Prof. Martin Schmidt, and was a postdoctoral researcher in the SCALE AI Chair in Data-Driven Supply Chains at Polytechnique Montréal, with Prof. Thibaut Vidal.
