Charles SOUSSEN

I was born in France in 1972. I graduated from the Ecole Nationale Supérieure en Informatique et Mathématiques Appliquées, Grenoble, France (ENSIMAG) in 1996. I received the PhD degree in Signal and Image Processing from the Laboratoire des Signaux et Systèmes (L2S), Université de Paris-Sud, Orsay, France, in 2000, and the Habilitation à Diriger des Recherches at University of Lorraine, France, in 2013. I was Associate Professor at Paris-Sud University from 2001 to 2005 and at University of Lorraine from 2005 to 2017. I have been with L2S since 2017. My research interests are in inverse problems and sparse approximation. Since Jan. 2025, I am the head of the teaching Departement of CentraleSupelec (Signal-Information-Communications). / CentraleSupélec
