Latest news

  • New preprint Direct search based on probabilistic descent in reduced spaces, co-authored with L. Roberts.

  • Completed a three-week research visit to the United States, that included stops at Lehigh University, University of Michigan, University of Wisconsin-Madison (a really quick one!) and Johns Hopkins University. I also attend the INFORMS Optimization Society Conference in Greenville, SC. Many thanks to every person that I got to meet and exchange with, and a special thank you to my hosts Luis Nunes Vicente, Albert Berahas and Christian Kümmerle!

  • New preprint A nonlinear conjugate gradient method with complexity guarantees and its application to nonconvex regression, co-authored with R. Chan--Renous-Legoubin.

    Research interests

    My research essentially revolves around the field of numerical optimization and its applications, particularly in complex systems and data science.
    My current work aims at developing efficient nonconvex optimization algorithms, with a focus on incorporating randomness (typically within linear algebra techniques), and establishing complexity guarantees for those frameworks.
    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.
