Présentation
Received the State Engineering degree from Ecole Nationale Polytechnique (ENP), Algiers, Algeria, in 2003, the M.S. degree in signal processing from Supelec and Paris XI University, Orsay, France, in 2004, and the Ph.D. degree in signal and image processing from ENST Paris, France, in 2007. In 2007, he joined the Signal & Communications department of IMT Atlantique (Telecom Bretagne) , Brest, France as an Associate Professor, and then Professor, since 2015. He was a Visiting Researcher at Fujitsu Laboratories, Japan and the department of Electrical and Electronic Engineering of The University of Melbourne, Australia in 2010 and 2015, respectively. His research interests are blind source separation, blind system identification and equalization, compressed sensing, sparse signal processing, statistical signal processing, wireless communications, and adaptive filtering.
