University professor at Clermont Auvergne University, Dr. Guillin is a specialist in probability, with significant results on functional inequalities, the concentration of measurement, and convergence towards the equilibrium of Markovian dynamics. Dr. Guillin works on the interactions between probabilities and partial differential equations by studying the propagation of chaos (granular medium, Landau equation). Dr. Guillin also developed multidisciplinary collaborations with volcanologists, ecologists, and doctors. He has been deputy director of the Blaise Pascal Mathematics Laboratory since 2014. As part of the Auvergne-Rhône-Alpes Mathematics Research Federation, of which he was director from 2017 to 2020, he led the creation of the Mathematics Institute for planet Earth, of which he has been the executive director since 2021.
