About
Dr. Kangyao Wen is a leading researcher in the reliability and thermal management of wide-bandgap power semiconductors, with a primary focus on Gallium Nitride high-electron-mobility transistors (GaN HEMTs). His work addresses critical challenges in high-power applications, including AI power supplies and robotics, where device degradation from electrical and thermomechanical stresses poses significant reliability risks. Dr. Wen’s most notable contribution is the development of a self-calibrating temperature-sensitive electrical parameter (TSEP) technique for junction temperature monitoring and remaining useful life (RUL) prediction in GaN HEMTs. This innovation enables real-time, non-invasive health assessment of power devices, directly improving system safety and longevity. His research, published in 2025, has already garnered attention for its practical impact on predictive maintenance and device qualification. By bridging the gap between fundamental degradation mechanisms and applied reliability engineering, Dr. Wen’s work is shaping the next generation of robust, high-efficiency power electronics for demanding industrial and AI-driven environments.
