My research is focused on integrable (or exactly solvable) systems and special functions. I am particularly interested in integrable many-particle systems of so-called Calogero-Moser type and their connections with (multivariate) hypergeometric functions and orthogonal polynomials, symmetric functions and random matrix theory.
