Présentation

After a Ph.D. in Chemistry, Environment and Health and a post-doctoral position in Florida State Univ. in Thalahassee (USA), Valérie Héquet arrived in 2000 at the Ecole des Mines de Nantes at the Department of Energy Systems and Environment. She is currently Professor at IMT Atlantique (previously Ecole des Mines de Nantes). She is a member of the UMR CNRS laboratory GEPEA (Génie des Procédés-Environnement et Agro-alimentaire) where she has in charge the team “Air and Water Treatment and Metrology”. Her main domains of research are on the mass transfers and advanced oxidation mechanisms especially occurring in photocatalytic processes. The aims are the removal of low concentration organic compounds in mixture in indoor atmospheres and the removal of micro-pollutants at low concentrations in aqueous matrix. She is scientific coordinator in several French research projects and she was leader of a work-package of a European Project Clean Water (FP7-ENR-NMP). These project objectives were to evaluate the activity of visible-nano-catalysts under solar irradiation for water detoxification and efficiency towards emerging pollutants. Up to now, she has published more than 40 papers in peer review journals (h-index of 15) and has attended to numerous national and international conferences (more than 80 invited, oral and poster communications).
