I've been an Associate Professor (Professeur associé) at the Applied Math department of École polytechnique since September 2013. I've been doing my research at the CMAP of École polytechnique. I'm the cohead of the SIMPAS team (Signal IMage numerical ProbAbilities Statistical Learning). I'm also the head of the "Data Scientist" chair of École polytechnique created in octobre 2014 by École polytechnique, Keyrus, Orange and Thales, and supported by Fondation de l'X. This chair is dedicated to the Data Sciences training programs.
I've done a Signal Processing PhD with Stéphane Mallat at the centre de mathématiques appliquées de l'École polytechnique. The subject of the thesis is the introduction of geometry in image representation. I defended it on December the 19th 2002 : its title is Bandelettes et représentations géométriques des images (Bandelets and geometric representation of images). In 2002-2004, I worked as a "post-doc" in a joint-project between the CMAP and Let It Wave, a company created by Stéphane Mallat, Christophe Bernard, Jérôme Kalifa and myself to exploit our research on bandelets. I consulted for the company till its closure in 2012 (even after its acquisition by Zoran and then by CSR). From 2004 to 2010, I was a "Maitre de Conférence" (Assistant Professor) at the university Paris Diderot (Paris 7) in the "laboratoire de Probabilités et Modèles Aléatoires" (Statistics team). From 2010 to 2013, I was a "Chargé de Recherche" (Research Associate) at the project SELECT of Inria Saclay, a project in which I had already worked in 2009-2010. I defended my HdR (Habilitation à Diriger des Recherches) entitled "Some (statistical) applications of Ockham's principle" the 19th of march 2013.
