Mis à jour le

Since February 1st, 2015, I am professor at ISAE in Probability and Statistics in the department of complex systems. My research interests lie in applied probability, and I am currently working on renormalization techniques (functional law of large numbers and central limit theorem) applied to branching processes and models of communication networks.
