Vita
I am a CNRS researcher at the interface of mathematics and computer science. My current host lab is the Laboratoire J. A. Dieudonné of Université Côte d’Azur located in the beautiful city of Nice.
My research interests cover in particular the mathematical foundation of machine learning, especially linked to optimization. In particular, I work on graph machine learning, algorithmic differentiation, (stochastic ∨ bilevel ∨ nonsmooth) optimization. I am currently an Area Chair for NeurIPS, ICML, ICLR, and Action Editor for TMLR. I am also PI of the research projet ANR PRC ANR MAD and 3IA Côte d’Azur chairholder. More information are available on my About page.
