Douglas C. Hopkins
Research Professor, Dir. PREES Lab
Biography
Prof. Hopkins' Primary Research Areas:
• Very High-Frequency, Ultra-High-Density power electronic systems, Integrated Power Electronics*, Wide Band Gap (WBG: GaN & SiC) devices, and Advanced Packaging**
• Solid-State Protection (e.g. SSCBs) and Harsh-Environment power electronics (e.g. automotive and military)
* IEEE/EPS Heterogeneous Integration Roadmap (HIR) Chapter 10 - "Integrated Power Electronics"
** Power electronics packaging, organic- and ceramic-based circuits, high temperature(>300˚C) circuits integrated ceramics and metal matrix composites
Professor Hopkins has been with the ECE Department since 2011, is Director of the Laboratory for Packaging Research in Electronic Energy Systems (PREES), part of the FREEDM Systems Center, and is an affiliate faculty with the Center for Additive Manufacturing and Logistics (CAMAL). He received his Ph.D. from Virginia Tech (1989). He has held Visiting Faculty appointments with the Army, NASA, Lawrence Livermore, and the Ohio Space Institute, was a reviewer with the Nat’l Academy of Science. His early career was at the R&D centers of General Electric and Carrier Air-Conditioning companies, and has had numerous consulting projects with Emerson, Grundfos, Eaton, and Verizon among others. He co-founded DensePower, LLC as president and CTO, and has published over 200 journal and conference articles, and conference tutorials and workshops.
Dr. Hopkins founded/cofounded the: IEEE EPS/PELS joint Power Packaging Committee (1994), Int’l Wksp on Integrated Power Packaging (IWIPP, 1998), IEEE/IMAPS/PSMA “Int’l Symp. on 3D Power Electronics Integrations and Manufacturing” (3D-PEIM, 2016), and the IMAPS “International Symposium on Advanced Power Electronics Packaging (APEPS, 2021). He received the IMAPS Outstanding Educator Award (2013), is an IMAPS Fellow (2007) and member of the IMAPS Executive Council (2019-2021). He also chairs the EPS Power & Energy TC (2022-).
Prof Hopkins also conducts engineering consulting and expert witness activities through DCHopkins & Associates, LLC. Further information is available from www.DCHopkins.com
