I was born in Lorraine, France in 1977 and grew up in Kasserine (Tunisia), Dakar (Senegal) and Antananarivo (Madagascar), where I obtained my baccalauréat in 1995, at Lycée Français de Tananarive. From Sep. 1995 to June 1997, I attended classes préparatoires at Lycée Henri Poincaré (Nancy, France). In Sep. 1997, I entered French engineering school École Centrale de Nantes, from which I graduated in June 2000; I was an intern at Maroc Telecom R&D (Rabat, Morocco) during summer 1999. In Sep. 2000, I also obtained a DEA (MSc) in Automatique et Informatique Appliquée jointly from École Centrale de Nantes and Université de Nantes. From Oct. 2000 to Oct. 2003, I was a PhD student with the signal processing group ADTSI at IRCCyN (Nantes, France), under the supervision of Prof. C. Doncarli. From Nov. 2003 to Mar. 2006, I was a research associate with the Signal Processing Laboratory at University of Cambridge (UK). From May 2006 to Feb. 2007, I was a research engineer with the start-up company Mist-Technologies (now Audionamix) in Paris. In March 2007, I joined Laboratoire Traitement et Communication de l'Information (LTCI) at Télécom ParisTech, first as a research associate and then as a CNRS tenured research scientist (Chargé de Recherche) in Nov. 2007. I was a visiting scientist with Mitsubishi Electric Research Laboratories in Cambridge, Massachusetts) during summer 2012.Select professional activities :
In January 2013, I joined the signal processing group at Laboratoire Lagrange (CNRS, Observatoire de la Côte d'Azur & Université de Nice Sophia-Antipolis) in Nice, France.
I am a photography enthusiast and some of my work can be seen on my blog.
