Saïd YAGOUBI

Biography

Saïd Yagoubi is currently a lecturer in materials science at the University of Paris-Saclay. He obtained his PhD in solid-state chemistry in December 2004 from the University of Lille, France, within UCCS laboratory. After two years as a temporary teaching and research associate in Lille, he completed his postdoctoral studies from 2006 to 2008 at the Institute of Transuranium Elements (ITU), JRC-European Commission, in Karlsruhe, Germany. During his postdoctoral research program, he investigated the behaviour of 5f electrons and superconductivity in metals and intermetallic compounds under pressure using synchrotron radiation. Currently, within the Paris-Saclay University, Saïd Yagoubi is manager of Master 1 Energy-Materials in the Energy section. Dr. Saïd is affiliated to the LEEL laboratory at the CEA Paris-Saclay. His current research involves exploring advanced battery materials, including all-solid-state batteries and nanostructured materials. He uses a multi-scale analysis, including EIS and advanced solid-state NMR, to understand the relationship between synthesis, structure, and transport properties.
