Régis Cottereau, Chargé de Recherche CNRS


Je suis chargé de recherche CNRS au laboratoire MSSMat (CNRS, CentraleSupélec, Université Paris-Saclay). Mes activités de recherche s'organisent autour de trois grandes thématiques : (1) Couplages de moèles probabilistes, (2) Changement d’échelles en mécanique probabiliste, et (3) Calcul haute performance et estimation d’erreur. Mon travail est essentiellement numérique et j’ai considéré des applications pratiques variées : vibrations ferroviaires (en lien avec la SNCF I&R et la RATP), matériaux polycristallins, érosion, transports sédimentaires, stockage et transport du CO2 (en lien avec l’INERIS), entre autres. Cependant, la majorité des applications que je considère sont issues de l’ingénierie parasismique (en lien avec EDF R&D et d’autres acteurs de la filière nucléaire, et avec le bureau d’études Tractebel-Coyne et Bellier) et de la géophysique.
