CNRS researcher at the Computer Science Department of ENS (DI ENS), Université PSL.

I am interested in various aspects of machine learning, statistics and signal processing. In the deep past (1990s), I started in the domain of speech and audio processing. More recently (2000s), I contributed to Bayesian methods, Markov Chain Monte Carlo and to some applications in natural language processing. Most of my recent works (2010s) are related to online learning and multi-armed bandit models.

I am affiliated to the newly created Centre Sciences des Données (CSD) at ENS. I am also adjunct professor at Université PSL, where I am in charge, with Benjamin Negrevergne, of the master program IASD.

I also serve as scientific deputy director of the CNRS division of Information Sciences and Technologies (INS2I), where I am in charge of actions in the field of information sciences at large (on topics such as artificial intelligence, cybersecurity and quantum computing).
