About me

I am a third year PhD student in Applied Mathematics at ENSAE Paris. My research focuses on robust estimation, high-probability guarantees, statistical learning theory and concentration inequalities. I am supervised by Alexandre Tsybakov and Jaouad Mourtada. I am also a teaching assistant at ENSAE Paris, ranked among the top 1% of TAs at the school.
