About me

I am an Assistant Professor at the Laboratoire des Signaux et Systèmes at CentraleSupélec. Before this role, I was a post-doctoral researcher at Inrae Montpellier, working on the ASCAI project led by Nicolas Vezelen and Alexandra Carpentier. I completed my PhD in 2022 at the Laboratoire de Mathématiques d'Orsay of Paris-Saclay University, under the supervision of Gilles Blanchard and Sylvain Arlot.
My interests are predominantly centered around the domains of Online Learning and Bandit Theory.
