About me

I am a PhD student in machine learning in the Center for Applied Mathematics (CMAP) at École Polytechnique, under the supervision of Stéphane Gaïffas and Erwan Scornet.

My primary research subject is the theoretical analysis of Random Forest algorithms. I am also interested in online learning, in particular in prediction with expert advice and online optimization.
