I am a researcher at INRIA, leading since 2011 the SIERRA project-team, which is part of the Computer Science Department at Ecole Normale Supérieure, and a joint team between CNRS, ENS and INRIA. I completed my Ph.D. in Computer Science at U.C. Berkeley, working with Professor Michael Jordan, and spent two years in the Mathematical Morphology group at Ecole des Mines de Paris, I then joined the WILLOW project-team at INRIA/Ecole Normale Superieure/CNRS from 2007 to 2010. From 2009 to 2014, I was running the ERC project SIERRA, and I am now running the ERC project SEQUOIA. I have been elected in 2020 at the French Academy of Sciences. I am interested in statistical machine learning, and especially in optimization, sparse methods, kernel-based learning, neural networks, graphical models, and signal processing.
