Prof. Hopkins has over 20 years of experience in electronic energy systems. His early career was at the R&D centers of the General Electric and Carrier Air-Conditioning Companies in advanced power electronics systems for military and commercial applications up to the low MW range.
Prof. Hopkins received his Ph.D. from Virginia Tech where his research focused on zero-current switching converters and cermet packaging. Prior to joining NCSU, he was at the University at Buffalo (SUNY Buffalo) conducting research in high temperature power electronics (>350˚C) and packaging with aluminum-based composites. At NCSU he created the Laboratory for Packaging Research in Electronic Energy Systems (PREES) focusing on high-temperature, high-frequency, 3D packaging using composite materials primarily for wide band gap power semiconductors (e.g. GaN and SiC) .
Prof Hopkins held Visiting Faculty appointments with the Army, NASA, and the Ohio Space Institute. He was co-founder of DensePower, LLC, and conducts expert witness activities through DCHopkins & Associates, LLC. He has published over 100 journal and conference articles, a number recognized with awards. Further information is available from www.DCHopkins.com
