CNRS Research Director and Professor at the Ecole Polytechnique, Director of the Laboratoire de Méteorologie Dynamique (LMD) (Ecole Polytechnique in co-supervision with CNRS, ENS Paris and Sorbonne University) and of the Energy4Climate Interdisciplinary Centre at the Institut Polytechnique de Paris, my research focuses on meteorology, the study of Mediterranean climate variability and evolution and energy transition. I have coordinated many national and international programmes on Mediterranean meteorology and climate and their impacts on water and energy. I coordinate the HyMeX international programme to study the water cycle in the Mediterranean, which I represent within the World Climate Research Programme. At the Ecole Polytechnique, I manage the interdisciplinary research programme TREND-X on energy transition. I am the author of more than 140 book chapters and articles in international peer-reviewed journals. At the Ecole Polytechnique, I teach courses on climate change and renewable energy resources in the Polytechnicien cycle and at Master’s level, and I am responsible for the pedagogical aspects of continuing education on energy transition.
