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 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 second year (M2) of the master program IASD.

Recent News

(January 2025) In 2025-2026, the IASD and MASH M2 programs will merge and evolve with two tracks, IASD – Computer Science and IASD – Mathematics. Initial applications for the two tracks will be open from April 25 to June 23, 2025. The website will be updated with relevant information regarding the program and the application process in March 2025.

(December 2024) Master internship proposals for 2024-2025 Methods and Algorithms for Approximate Machine Unlearning, Privacy Auditing for Machine Learning, Reinforcement Learning for Optimizing Diffusion Models (applications for the three topics are now closed).

(Fall 2024) Interested in working on privacy preservation and robustness in machine learning and looking for postdoc position starting in 2025? Contact me (with CV an references) for further info.
