Research activities (sorry, only french text)
Mon travail de recherche porte sur la modélisation et l’analyse numérique des ondes acoustiques et électromagnétiques dans les milieux complexes. J’explore ce sujet selon trois directions : les méthodes asymptotiques, les formulations intégrales et la décomposition de domaine.
