Select professional activities :
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
. From Sep. 1995 to June 1997, I attended classes
(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
(Nantes, France), under the supervision of Prof. C.
Doncarli. From Nov. 2003 to Mar. 2006, I was a research associate
with the Signal
(UK). From May 2006 to Feb. 2007, I was a research
engineer with the start-up company Mist-Technologies
Paris. In March 2007, I joined Laboratoire
et Communication de l'Information (LTCI)
, first as a research associate and then as a CNRS
tenured research scientist (Chargé
) in Nov. 2007. I was a visiting scientist
with Mitsubishi Electric Research
in Cambridge, Massachusetts) during summer
In January 2013, I joined the signal processing group at
(CNRS, Observatoire de la Côte d'Azur
& Université de Nice Sophia-Antipolis) in Nice, France.
Laboratoire Lagrange carries out interdisciplinary research in the
fields of astrophysics, mechanics and signal processing.
I am a photography enthusiast and some of my work can be seen on my
signal processing and machine
learning, for denoising, source separation, inverse
problems, in particular with audio
applications, and including statistical estimation,
Bayesian inference, optimization, stochastic simulation,
variational approximations, latent variable models, independent
component analysis, sparse component analysis, nonnegative matrix
factorization, time-frequency representations.
cited papers, as of Google
software and other
MATLAB code associated with many of my papers can be found on my publications
I am with Emmanuel
Vincent and Rémi
Gribonval one of the creators of the widely used blind
source separation evaluation Matlab toolbox BSS_EVAL.
I run the Latent Variable Analysis and Signal Separation LVA/ICA
