Welcome to my personal webpage!
I am a CNRS researcher at DMA (ÉNS Paris) and a part-time professor in the Department of Applied Mathematics at École polytechnique. I study scaling limits of discrete random models. You can find my CV here. A photo of me proving a theorem.

Some links
- Mathematics club (in French) for secondary-school students, meeting on Saturday afternoons at ENS Paris.
- Mathematical olympiads (secondary-school level): see here and here.
- Mathematic Park: short mathematics courses on various topics, at preparatory-class or university level.
A simulation
Here is an example of a random object I study:
The first figure is a subcritical Galton–Watson tree, called nongeneric with 24045 vertices, while the second is a uniform tree with 27179 vertices (approximating Aldous’ Brownian tree).
