Présentation
Je suis né en France in 1972. Je suis diplômé de l'Ecole Nationale Supérieure en Informatique et Mathématiques Appliquées, Grenoble (ENSIMAG) en 1996. J'ai obtenu ma thèse en traitement du signal et des images au Laboratoire des Signaux et Systèmes (L2S), Université de Paris-Sud, Orsay, en 2000, et mon Habilitation à Diriger des Recherches à l'Université de Lorraine en 2013. J'ai été Maître de Conférences à l'Université de Paris-Sud et au LIMSI entre 2001 et 2005, puis à l'Université de Lorraine et au CRAN entre 2005 et 2017. Je suis Professeur à CentraleSupélec et au L2S depuis 2017. Mes thèmes de recherche concernent les problèmes inverses et l'approximation parcimonieuse. Je suis le responsable du Pôle Signaux et Statistiques du L2S depuis 2020. J'ai été membre du Comité National de la Recherche Scientifique (CoNRS), [section 7]((http://section7.cnrs.fr/) de 2019 à 2023. Je suis éditeur associé pour le journal IEEE Transactions on Signal Processing depuis octobre 2023. Ma page web se trouve ici.
