Position (2026/09) After 7 wonderful years at Université Paris Dauphine-PSL, I have joined Université Gustave Eiffel as a professor (professeur des universités). My research affiliation is now the Laboratoire d'Informatique Gaspard Monge.

Research interests

My research essentially revolves around the field of numerical optimization and its applications, particularly in complex systems and data science. In addition to optimization, my work relies heavily on linear algebra techniques and randomized methods.
Lately I have been interested in analyzing certain classes of nonconvex optimization problems and developing efficient algorithms with complexity guarantees for solving those problems. I am also highly interested in derivative-free optimization and its applications to solving simulation-based problems.
