Sombel Diaham obtained an MSc and Ph.D. in Electrical Engineering from the University of Toulouse, France, in 2005 and 2007, respectively. In 2008, he joined the Laboratory on Plasma and Conversion of Energy (LAPLACE) as an associate professor. He is an expert in electrical isolation for HV power and integrated electronics. He works on polymer films, thin inorganic layers, and encapsulation resins. His interests concern the physics of dielectrics (charge injection, breakdown mechanisms), electrical characterizations, properties-process relationships, modeling and multi-stress aging of insulation, and the application to real devices. Dr. Diaham develops advanced composites and nanocomposites to enhance devices’ and systems’ reliability. In this role, he designs field grading composites tailored by (di)electrophoresis and applies them to power electronics isolation.
