CNRS senior scientist (directeur de recherche)

Institut Elie Cartan de Lorraine, Université de Lorraine, Nancy, France

News:

• I am an organizer of the Probability and Statistics Seminar at IECL, Nancy.
• I have been promoted to senior scientist (Directeur de Recherches) at CNRS.
• A bit less new, but still recent: I have given a mini-course at Journées ALÉA (Marseille, March 2023) on "Logical limit laws for random permutations" : Lecture notes in French are available here (including exercices on page 11, see here for the solutions), I also used slides for the last part of the lecture (non-convergence law for uniform random permutations).

Some research topics:

• Random permutations, patterns and permutons (see a picture of the Brownian separable permuton);
• 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 generalizations (in particular quasi-symmetric functions) ;
• Linear extensions, hook formulas, $P$-partition theory.

Short CV:

• 2023-now: CNRS senior scientist (directeur de recherche) in IECL, Nancy.
