Research topics

•    The study of random matrices, very active domain of research, which has applications in combinatorics, number theory, physics, statistics and telecommunication.
•    Asymptotic analysis of orthogonal polynomials and Hankel, Toeplitz and Fredholm determinants, Riemann-Hilbert problems.
•    Integrable differential equations, such as Painlevé equations (solutions to them are called the special function of the 21st century) and the Korteweg-de Vries equation (which describes shallow water waves).
•    Diffusion processes, such as Brownian motion, and determinantal point processes.
