Sombel Diaham received his M.Sc. degree in 2005 and his PhD degree in 2007 in Electrical Engineering both from the University of Toulouse, France. In 2008, he joined the University of Toulouse and the LAPLACE Research Institute as an Associate Professor in Electrical Engineering. His research field deals with insulating polymers and composites for high voltage power electronic applications. He studies the electrical properties of polymers and elastomers for power devices and power modules isolation and among others he has worked on polyimide for 15 years so far. His interests concern the physics of dielectrics, electrical characterizations, properties-process relationships, electrostatic modeling and aging of polymers under high electric field. Meanwhile, he develops and investigates composites and nanocomposites for power electronics. On this topic, he consecutively obtained two highly selective ANR national researcher programs (2013 and 2018) to work on field grading composites tailored by electric field. In 2018, he has been invited as Researcher in the European R&D Centre of Analog Devices in Limerick (Ireland) to work on high voltage digital isolators based on polyimide. In 2019, he obtained an International Young Scientist Fellowship funded by the National Natural Science Foundation of China (NSFC) for research activities on nanocomposites for HVDC in collaboration with the Northeast Electric Power University in Jilin. From 2019-2021, he obtained one of the prestigious Marie Skłodowska-Curie Individual European Fellowship (MSCA-IF) to pursue the development of advanced isolation technologies for digital isolators with Analog Devices and the Bernal Institute of the University of Limerick. Sombel Diaham is an IEEE Dielectrics and Electrical Insulation Society member (DEIS). He has been an executive committee member for the organization of the IEEE CEIDP 2018 and 2019 conferences as the Publication and Publicity Chair and has been an elected Board member of this conference since 2016. He has been the coordinator of the French Research Network on Dielectrics since 2016. He authored and co-authored more than 40 papers in international scientific journals, more than 100 international and national conference papers, 2 book chapters and 7 patents.
