About me
Since September 2024, I have been a postdoctoral researcher at the Optimal Lab at KAUST.
Prior to this, I was an Assistant Professor at the Laboratoire des Signaux et Systèmes at CentraleSupélec.
Before that, I worked as a postdoctoral researcher at Inrae Montpellier on the ASCAI project, led by Nicolas Vezelen and Alexandra Carpentier.
I obtained my PhD in 2022 from the Laboratoire de Mathématiques d'Orsay at Paris-Saclay University, under the supervision of Gilles Blanchard and Sylvain Arlot.
My research focuses on Online Learning and Bandit Theory, with an emphasis on theoretical aspects and algorithmic development.
