SHORT CV

I graduated from Ecole Normale Supérieure, Paris, in 1997. I prepared my Ph.D. under the supervision of S.Mallat jointly at the Centre de Mathématiques Appliquées of Ecole Polytechnique (with E. Bacry) and at IRCAM, Paris (with X. Rodet & Ph. Depalle). I obtained my Ph.D. degree in applied mathematics from the Université Paris-IX Dauphine in 1999. In 1999-2000 I visited the Industrial Mathematics Institute at the University of South Carolina as a postdoc in the Wavelet Ideal Data Representation NSF/KDI research initiative. In 2000 I joined INRIA as Chargé de recherche at IRISA, Rennes in the SIGMA2 project. Since 2001 I am affiliated with the METISS project on audio signal processing. I obtained my Habilitation à Diriger des Recherches (HDR) in Mathematics from the Université de Rennes I in 2007. Since 2009 I hold a position of Directeur de Recherche (Senior Research Scientist) with INRIA. In 2011 I was awarded the Blaise Pascal Award of the GAMNI-SMAI by the French Academy of Sciences. I obtained in 2011 a Starting Grant from the European Research Council.
