Directeur adjoint du laboratoire LEGI (UMR 5519), je suis en charge des relations avec l’UAR et le Labex OSUG, des carrières ITRF/ITA, ainsi que des enjeux de Développement Durable et de Responsabilité Sociétale (RSE) au sein du laboratoire.
Expert en calcul scientifique, j’accompagne depuis plus de quinze ans le développement et l’optimisation de codes haute performance, qu’ils soient propriétaires, communautaires ou développés en interne. Mes travaux portent notamment sur le transport sédimentaire, les machines tournantes (éoliennes, hydroliennes) et l’écoconception des services numériques.
Au sein du laboratoire, je co-encadre plusieurs thèses et assure le rôle de référent pour le développement et l’analyse de données. Je suis également mainteneur du solveur open-source sedFoam, basé sur la plateforme OpenFOAM, et j’anime le réseau régional des utilisateurs de cet outil, en lien avec la communauté Foam-U, dont je suis membre du conseil d’administration.
Par ailleurs, je participe activement au GDRS EcoInfo (CNRS), où je contribue à l’évaluation de l’impact environnemental des systèmes numériques et à la promotion de pratiques de calcul plus sobres et durables. Dans ce cadre, je suis également impliqué dans MATINFO, en tant que pilote du groupe de travail Développement Durable et membre du groupe de travail Station de travail, avec pour objectif de réduire l’empreinte environnementale des infrastructures informatiques de la recherche.
