NEWS: * #### **We are organizing a PhD school on robust optimization on June 3-5 2024: https://roschool24.sciencesconf.org/** #### **Short CV** I graduated in Mathematics from the Université Libre de Bruxelles, and in Operational Research from the University of Edinburgh. My thesis was done at the GOM research group from the Université Libre de Bruxelles, under the supervision of Bernard Fortz, Martine Labbé, and François Louveaux. During my PhD, I spent some time in Rio de Janeiro working with Claudia Sagastizabal. After my thesis was defended in Feburary 2011, I spent a couple of months at the Universidade de Aveiro, followed by a postdoctoral stay at the CMUC from the Universidade de Coimbra. I was a CNRS researcher at Heudiasyc from October 2012 to January 2015 and joined the LIRMM in February 2015. I am a senior researcher (directeur de recherche) since 2020. #### **Research interests** My research interests lie at the junction of combinatorial optimization and mathematical optimization. I study theoretical properties (complexity, approximation) and numerical properties (exact algorithms) of optimization problems motivated by real applications (telecommunications, electrical power, production, transportation, ...). I am more particularly interested in the interplay between uncertainty and discrete optimization. #### **PhD Students** - Igor Malheiros (2022 - ...): Around efficient robust optimization for logistics and transportation - Camille Grange (2021 - ...): Around quantum combinatorial optimization.

No review!** <img src="https://nofreeviewnoreview.org/static/img/nfvnr-button.svg" alt="No Free View No Review" width="20%" height="20%"> I believe our publishing system should evolve towards a different publishing model in which all scientific publications are freely available to readers as open access, without charging authors unfair prices. For that reason, I do not wish to participate in editorial boards or program committees that rely on for-profit publishers. Despite this, I may still referee papers (reluctantly) for such journals, as I still submit papers to them due to the lack of diamond/fair open access alternatives in my community. A detailed argumentation on this issue is well described [here](https://a3nm.net/work/research/openaccess/). #### **Open Journal of Mathematical Optimization (OJMO)** If you have ever dreamed of a fair open access journal managed by mathematical optimizers for mathematical optimizers, publishing high-quality works in open access free of charge, you muck check out [OJMO](https://ojmo.centre-mersenne.org/)'s website! #### **Community service** - I am a board member of the current (2021-2026) [Section 06](https://cn6.fr/) of the National Committee for Scientific Research (CoNRS). - I am a board member of [Free Journal Network](https://freejournals.org/), an organization whose main purpose is to promote scholarly journals run according to the Fair Open Access mode. - I am part of the scientific committee of the gdr-ro, regarding [open science](http://gdrro.lip6.fr/?q=node/243) and the robust optimization axis. - I am head of research team [MAORE](https://www.lirmm.fr/equipes/maore/).
