Umesh K. Mishra serves as the Dean of The Robert Mehrabian College of Engineering and holds the Richard A. Auhll Professorship in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara. He is a member of the National Academy of Engineering and directs both the Solid State Lighting and Energy Electronics Center and the ONR MURI Center on wide bandgap semiconductor based electronics.
His educational background includes:
- PhD in Electrical Engineering from Cornell University
- MS in Electrical Engineering from Lehigh University
- BTech in Electrical Engineering from Indian Institutes of Technology Kanpur
Mishra's research program centers on wide bandgap semiconductors, particularly gallium nitride (GaN) technology. His work spans GaN electronics, opto-electronics, materials science, oxide-based electronics, non-stoichiometric semiconductors, vacuum microelectronics, and InP & GaAs based electronics. His group has pioneered N-polar GaN technology, developing transistors demonstrating output powers of 6.7 W/mm at 94 GHz and 20.7 W/mm at 4 GHz. The research bridges fundamental materials science with practical applications in high-frequency communications and power electronics, utilizing metal-organic chemical vapor deposition (MOCVD) for high-quality GaN film growth.
His recent publications reveal continued innovation across multiple fronts of GaN technology, with significant work on N-polar devices, advanced transistor designs, thermal management solutions using diamond cooling, and novel characterization methods. These publications demonstrate the group's leadership in both materials science and device engineering aspects of wide bandgap semiconductors.
Mishra has received numerous prestigious honors:
- ISI Highly Cited Researcher
- Welker Award for Development of Gallium Nitride High Power Electronics
- ISCS Quantum Device Award
- IEEE David Sarnoff Award for Development of Gallium Nitride Electronics
- IEEE Jun-ichi Nishizawa Medal
- Elected Foreign Fellow, Indian National Academy of Engineering
As an advisor, Mishra leads a substantial research group with numerous PhD students and professional researchers including Dr. Stacia Keller (Principal Development Engineer), Dr. Karine Hestroffer (Assistant Project Scientist), and Dr. Xiang Liu (Assistant Project Scientist). His group has secured significant research funding from organizations including the Office of Naval Research and likely other federal agencies and industry partners given the applied nature of their work. The laboratory facilities are located in the Engineering Science Building at UCSB, supporting both fundamental materials research and device fabrication.
The Mishra Research Group operates within the Solid State Lighting and Energy Electronics Center, specializing in metal-organic chemical vapor deposition for growing high-quality GaN films and developing advanced transistor structures. Their work has made significant contributions to both academic knowledge and commercial semiconductor technology, with applications spanning high-frequency communications, power electronics, and optoelectronic devices.
