I am a CNRS senior researcher; formerly in the LIMSI Lab at Université Paris-Saclay, I am currently affiliated to the DI ENS Lab, 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 are related to online learning methods or multi-armed bandit models.

I am also scientific deputy director of the CNRS division of Information Sciences and Technologies (INS2I), where I coordinate activities in the field of information sciences at large (e.g., in quantum computing, cybersecurity or artificial intelligence).
