Welcome to my personal webpage!

I am a CNRS researcher and part time Professor at École polytechnique. My research interests are centered around the scaling limits of various discrete random structures such as random walks, random dissections and random trees. You can find my CV here.

A simulation

An example of a random object I have been studying:

The first figure is a particular type of subcritical Galton-Watson tree, called nongeneric, with 24045 vertices. The second figure is a uniform tree with 27129 vertices (approximating Aldous' Brownien Continuum Random Tree).
