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).

News

(May 2023) Registrations for the IASD program are currently open.
