معرفی
Rachelle Hanna serves as a Senior Lecturer in the Department of Energy, Water and Environmental Sciences at Grenoble Institute of Technology since 2015, focusing on dielectric materials under extreme operational conditions. Her work bridges fundamental charge transport mechanisms with practical applications in high-voltage power systems and space technologies.
Education
- Ph.D. in Materials & Electrical Engineering, Université de Toulouse (2012)
Research Focus: Dr. Hanna investigates charge transport and aging effects in insulators (polymers, ceramics, gels, liquids, gases) subjected to ionizing radiation (2 eV–400 keV), electric fields, and temperatures up to 400°C. Her expertise spans dielectric characterization, space charge dynamics, HVDC systems, and breakdown phenomena, with direct relevance to power electronics, aerospace engineering, and energy infrastructure. Current work emphasizes material behavior under combined stressors for next-generation electrical systems.
Publication Trends: Recent publications (2022–2025) reveal concentrated efforts on power module thermal management using dielectric fluids and phase change materials, CO2 as sustainable insulation gas, and advanced modeling of streamer phenomena in gas-solid interfaces. Her work demonstrates strong industry applicability in medium-voltage equipment design and high-temperature power electronics.
