About me

I am a Neyman Visiting Assistant Professor in the Department of Statistics at UC Berkeley. Prior to that, I completed my PhD at CREST-ENSAE, under the supervision of Matthieu Lerasle and Jaouad Mourtada. I defended my Ph.D. on June 26, 2025. The manuscript can be found here.

I was also teaching coordinator at ENSAE for Statistics and Machine Learning courses during the academic year 2024-2025.

Research interests

Nonasymptotic statistics, statistical learning theory, empirical processes and concentration inequalities.
