My research domain concerns Applied Probability: I study the limit behaviors or macroscopic properties of complex systems built from microscopic random rules. See pictures below.
Keywords: Stochastic Geometry, Random Graphs and Percolation.
Member and scientific head of the Inria team PoPoPoP (created in Nov. 2025).
Associate member of the Laboratoire Paul Painlevé (the mathematics laboratory of Lille).
Associate editor of Sankhya (since 2025).
Member of RT MAIAGES (previously GDR GeoSto) since 2012. The RT MAIAGES is a french structure funded by CNRS and gathering people working on Stochastic geometry and image analysis. The RT MAIAGES is led by H. Biermé.
Some pictures of my research:
Simulation of a supercritical 5G telecommunication network in a urban media. Run by B. Henry.
Realization of the cluster of the (0,0) for the k-neighbor graph near the critical parameter. Run by B. Henry.
The hyperbolic Radial Spanning Tree in the Poincaré disk model. Run by L. Flammant.
The directed IDLA forest with sources on the vertical axis. In red: the tree of (0,0). Run by A. Rousselle.
The directed IDLA forest with sources on the vertical axis. In red: the tree of (0,0). Run by A. Rousselle.
On Last-Passage Percolation model, coexistence occurs with probability 6-8log2.
Coalescence of trajectories in the Directed Spanning Forest, with the Brownian Web as a scaling limit. Run by C. Tran.
PhD students:
