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

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 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 as well as for international relations).

(May 2020) In response to the current Covid-19 crisis, I am participating to the scientific initiative coordinated by Jamal Atif (learn more about Face Au Virus here).
