I received
both the D.E.A and the Ph.D. degrees in applied mathematics from University Paris 9 Dauphine in 1993 and 1996,
respectively. My Ph.D. dissertation was prepared at the Fractals Group of INRIA Rocquencourt, France. During 1997, I held a post-doctoral
position at the Department of Mathematics, Ecole
Polytechnique de Montréal, Canada.
From December 1997 to July 1999, I held a post-doctoral position at the Stochastic
Systems Group (SSG) of the Laboratory
for Information and Decision Systems (LIDS), Massachusetts Institute of Technology (MIT), Cambridge, USA. Since
October 1999, I have a permanent position at INRIA Lorraine within the Speech Group. Since October 2003, I am on
leave at CNRS with the SAMOVA team of IRIT.
My research interests include Statistical
Modeling and Estimation, Machine Learning, Bayesian Networks, Speech and
Speaker Recognition (and previously Wavelets, and Multifractal
Analysis).
