Associate professor at the University of Pau & Pays Adour, I am a specialist in theoretical chemistry, molecular modeling and numerical simulations at IPREM institute: Institut des Sciences Analytiques et de Physico-Chimie pour l’Environnement et les Matériaux. My research activities, in physical-chemistry, concern the understanding of macroscopic phenomena such as reactivity, thermochemistry or spectroscopy from a microscopic description of matter. Bridging the gap between the microscopic and the macroscopic worlds in order to explain the behavior of systems is the main philosophy of my research activity. To that end, I implement and combine molecular and numerical simulation methodologies at different time or space scales in order to catch the whole complexity of the system and the processes of interest.
