Magali REYTIER

Dr. Hab.​

Senior Expert​

Magali Reytier earned an engineering degree from ENSAM, with a concentration in structural calculations. She completed her PhD in materials science and engineering at École des Mines de Paris, ENSMP, and was granted accreditation to supervise research (Habilitation à Diriger des Recherches, or HDR) at Grenoble Alpes University. 

She has been with the CEA since 1995 and joined CEA-Liten in 2005. She directed the high-temperature hydrogen production laboratory until 2015, and the battery characterization laboratory until 2024.

Her research, which focuses on severe environments, is at the intersection of mechanics and materials science. Specifically, her focus has been on large-scale physics instruments at cryogenic temperatures, nuclear reactor vessels, and high-temperature electrolyzers and fuel cells. Her current priority is to advance the safety of batteries during accidents. 

In her capacity as Scientific Correspondent, she also now spearheads the battery safety roadmap and supervises several PhDs working on the topic.
