Gérard DELETTE

​Dr. Hab.​

Senior Expert​​

Gérard Delette graduated from engineering school École Centrale de Lyon in 1991. He is currently a Senior Expert in materials at CEA-Liten, where he focuses on powder metallurgy processes applied to a range of applications, including nuclear materials, solid oxide fuel cells (SOFCs), and soft and hard magnetic compounds. 

In his role as Scientific Director of the New Materials Technology Department at CEA-Liten, he drives the organization's advanced materials research strategy. He is co-author of 55 scientific publications in peer-reviewed journals and co-inventor of 17 patents.

He has also made significant contributions to technology transfer initiatives, including the Magnolia project to lay the groundwork for a magnet manufacturing industry.
