Research Experience
Currently, he is a Staff Research Lead at the Criteo AI Lab in Paris, managing a hybrid team of ML engineers and researchers. The team focuses on securing future-proof performance for Criteo AI engines due to the loss of granular user signal. Previously, he was a Research Scientist at the Lagrange Mathematics and Computing Research Center of Huawei, working with Alain Durmus and Eric Moulines.
Education
Obtained his Ph.D. in statistics on October 7, 2020, from the University of Toulouse, supervised by Pierre Chainais and Nicolas Dobigeon, within the SC group of the IRIT laboratory. In spring 2019, he was a research visiting scholar at the Department of Statistics of the University of Oxford, working with Arnaud Doucet.
Background
Current research interests lie in privacy-preserving machine learning and data valuation. During his time at Huawei, he worked on distributed/federated Bayesian approaches and privacy-preserving machine learning. His Ph.D. works focused on deriving a broad approximate statistical framework and associated Monte Carlo sampling approaches inspired by the variable splitting method in optimization (e.g., used by quadratic penalty approaches).
Miscellany
He has been affiliated with the ORION-B project, which gathers astrophysicists, data scientists, and statisticians in order to better understand the formation of stars in our universe.
