Dec. 2022 : Congratulations to Gilles Bareilles for passing his Ph.D. with flying colors! The jury included Nadia Brauner, Jalal Fadili, Claudia Sagastizábal, Jean-Charles Gilbert, Mathurin Massias, Claude Lemaréchal and his co-advisors: J. Malick and I.
Oct. 2022 : Waïss Azizian started his PhD. He is co-supervised by Panayotis Mertikopoulos and Jérôme Malick (CNRS & LJK, Grenoble) and will work on non-convex optimization for learning problems.
Mar. 2022 : Two interns have joined the team: Waïss Azizian (student at ENS Paris for his third internship with us!) and Julien Prando (student at UGA). They will both work on regularization aspects of distributionally robust methods.
Mar. 2022 : The second "Journée SMAI MAS-MODE" was a success: 7 talks and around 40 participants (in person!) at the intersection between optimization, probability, and statistics. website
Feb. 2022 : Victor Mercklé started his PhD. He is co-supervised by Ievgen Redko (Univ. St-Etienne) and will work on congestion games in networks.
Dec. 2021 : I defended my Habilitation à Diriger des Recherches (HDR) on Wed., December 15th! The jury was composed of Alexandre d'Aspremont (reviewer), Jérôme Bolte (reviewer), Adrian Lewis (reviewer), Jalal Fadili, Adeline Leclercq-Samson (president), and Julien Mairal. manuscript defense slides
June 2021 : Waiss Azizian (Student at ENS Paris) visited again our team for six weeks as part of his (previously online) internship to work on distributionally robust methods.
Nov. 2020 : Congrats to Dmitry “Mitya” Grishchenko for successfully defending his Ph.D.! The jury included Pascal Bianchi, Peter Richtarik, Julien Mairal, Samuel Vaiter, Alexander Gasnikov and his co-advisors: J. Malick, M. Amini, and I.
June 2020 : Waiss Azizian (Student at ENS Paris) visited our team for six weeks as part of his (previously online) internship to work on extragradient methods.
July 2019 : I was awarded an ANR JCJC grant (Young Research grant from the French Research Agency). The project is named STROLL: Harnessing Structure in Optimization for Large-scale Learning.
June 2019 : I am part of the chair on Optimisation and Learning, lead by Jerome Malick and Yurii Nesterov, funded by the Grenoble AI Institute.
June 2019 : Elnur Gasanov (Student at KAUST with P. Richtarik) visited our team for five weeks to work on distributed optimization.
Mar. 2019 : Alexander Rogozin (Student at MIPT Moscow with A. Gasnikov) visited our team for two weeks to work on distributed structure optimization.
Jan. 2019 : Mathias Chastan began his PhD between ST MicroElectronics and our team. He is co-supervised by A. Lam, J. Malick and I and will work on machine learning for industrial defects detection.
Right now, I am very interested in what happens when optimization algorithms arrive near non-differentiability points, both theoretically and practically. For instance, see:
