Principal Investigator
Spyridon “Spyros” Pavlidis, Ph.D.
Associate Professor, Department of Electrical and Computer Engineering
Spyridon Pavlidis is an Assistant Professor in the Department of Electrical and Computer Engineering at North Carolina State University, and the principal investigator for the Laboratory for Electronics in Advanced Devices and Systems (NCSU LEADS). He is affiliated with NCSU’s ME Commons Hub for Commercial Leap Ahead for Wide Bandgap Semiconductors (CLAWS) as well as the PowerAmerica, FREEDM and ASSIST Research Centers. He was previously a post-doctoral researcher in the School of Materials Science and Engineering at the Georgia Institute of Technology. Dr. Pavlidis received the PhD in Electrical and Computer Engineering from Georgia Tech, and the M.Eng in Electrical and Electronics Engineering from Imperial College London. His research interests lie at the intersection of semiconductor devices, novel materials and circuits with applications for high-frequency and power electronics, as well as sensing. In recent years, he has focused on the development of wide bandgap GaN and ultra-wide bandgap AlN semiconductors for next-generation electronics. He is the recipient of the 2022 NSF CAREER Award, the 2022 Bennett Fellowship and the 2015 EuMW Young Engineer Prize. He is an active member of the IEEE, serving on several technical program committees, as well as on the IEEE MTT-S Technical Committee on Microwave and Millimeter-Wave Solid State Devices.
