Last update November 2023

I am currently a postdoctoral researcher at New York University in the EnSuRe Research Group. I work with Siddharth Garg and Farshad Khorrami on Trustworthy Machine Learning. Prior to that, I was a postdoctoral researcher at INRIA and École Normale Supérieure (ENS) in the WILLOW project-team in Paris, France. I obtained my PhD in Computer Science in June 2021 at Université Paris Dauphine-PSL where I was advised by Pr. Jamal Atif, Pr. Yann Chevaleyre and Dr. Benjamin Negrevergne.
