CNRS senior scientist (directeur de recherche CNRS)
Institut Élie Cartan de Lorraine, Université de Lorraine, Nancy, France
News:
- The research project LOUCCOUM (for Large Objects Under Combinatorial Constraints and Outside Uniform Models) has been accepted for funding by the ANR (French National Research Agency).
The first workshop within the project took place at ENS Paris, from April 9th to 11th (open problem workshop). We will also be organizing a research school at CIRM in June 2026 (8th-12th).
Some research topics:
- Random permutations, patterns and permutons (see a picture of the Brownian separable permuton);
- Meanders and meandric systems;
- Central limit theorems for sums of weakly dependent variables:
I have recently introduced a new tool, weighted dependency graphs, to obtain this kind of results;
- Deviation probabilities, speed of convergence for combinatorial random variables, via mod-Gaussian convergence;
- Algebraic combinatorics, and in particular combinatorics in the symmetric group algebra and its representations (Young diagrams, factorizations in symmetric groups and associated graphs embedded in surfaces, Jucys-Murphy elements) ;
- Symmetric functions, including Jack polynomials, and their connection with map enumeration;
