Bio 

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 Département Signal-Image (TSI) at Télécom ParisTech, first as a research associate and then as a CNRS tenured research scientist (Chargé de Recherche) in Nov. 2007. I am a member of the Statistics and Applications group.

More precisely I am with UMR 5141 Laboratoire Traitement et Communication de l'Information (LTCI) which is a joint laboratory of TELECOM ParisTech (formerly known as École Nationale Supérieure des Télécommunications, ENST or Télécom Paris) and Centre National de la Recherche Scientifique (CNRS), physically located in Télécom ParisTech's buildings in Paris. Note that Télécom ParisTech belongs to Institut Télécom and is a member of ParisTech.


Selected responsabilities :
  • Since 2012 - Member of IEEE ``Machine Learning for Signal Processing" technical committee.
  • Since 2011 - Member of LTCI’s steering committee (Conseil de Laboratoire)
  • Since 2009 - Member of GdR-ISIS’ steering committee (CNRS funded French national network for Information, Signal, Images and Vision), in charge of the PhD students network (with Pierre Borgnat)
  • 2009 - 2012 - Scientific leader of the French ANR-Young Researchers project TANGERINE (Theory and applications of nonnegative matrix factorization)

I am a photography enthusiast and some of my work can be seen on my blog.
