Elise Berrier holds a PhD in Physics and after a post-doctoral stay at Leibniz Institut for Catalysis, Berlin (Germany), she obtained a position as CNRS researcher at UCCS, univ. of Lille. Her research topics focus on the characterisation of active phases under operating conditions, like supported oxides of molybdenum or rhenium for oxidation reactions or perovskite-based materials for 3-way catalysis. At present, she is the coordinator of the KNOWSKITE-X project funded by the European Commission and aiming at developing new oxide-based formulations for Solid Oxide Cells electrodes and carbon-based ones for supercapacitors
