Latest news

  • Teaching (2025/09) I am acting as deputy director (CS track) for the IASD (Artificial Intelligence, Systems, Data) Master program from Dauphine and PSL. I have also started my lectures on Optimization for Machine Learning in that program, as well as my classes on Mathematics for Data Science (first year of Master in Computer Science, Dauphine) and Optimization for Data Science (second year of Master in Computer Science, Dauphine). Off to a busy Fall!

  • Conference (2025/08) I attended the Optimization unplugged workshop held at EPFL (Lausanne, Switzerland) on August 25-27. A great event with terrific talks (including blackboard ones!). Many thanks to the organizers Nicolas Boumal, Lénaïc Chizat, Nicolas Flammarion and Andrew McRae!

    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.

    Short bio

  • September 1st, 2019: Joined Université Paris Dauphine-PSL and LAMSADE as a maître de conférences (equivalent to associate professor, with tenure granted on September 1st, 2020).

  • November 2016-August 2019: Postdoctoral research associate within the Wisconsin Institute for Discovery, in Madison, Wisconsin (USA). I was fortunate to work in the group of Stephen J. Wright.

  • November 4, 2016: PhD in applied mathematics from the university of Toulouse, delivered by the Université Toulouse III Paul Sabatier. Prepared at the Institut de Recherche en Informatique de Toulouse, under the joint supervision of Serge Gratton and Luís Nunes Vicente.
