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 am in charge of many training programs at Polytechnique: Data Science last year (PA), Datascience track of Paris Saclay and Data Science continuing education programs Starter Program of Polytechnique Executive Education. I am also the holder of the "Data Scientist" chair, a chair dedicated to training in the field of Data Science created in October 2014 by École Polytechnique, Keyrus, Orange and Thales and supported by the foundation of the X.
Aften an initial training in Mathematics at ENS Cachan, 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.
