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. 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 blog.
Statistical 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.
