Dr. Douglas C Hopkins

| Biography

Prof. Hopkins' primary research areas are:

* Very high frequency, high density power electronic systems

* Extreme environment electronics, and related solid-state protection

* Organic-based circuits for power and energy systems

* High temperature(>300˚C) metal-matrix composite packaging with integrated ceramics

* True 3D electronic packaging with flexible jet patterning

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. He is now developing an advanced electronics packaging laboratory.

He has also provided consulting to groups, such as Emerson, Grundfos, Lawrence Livermore, and Verizon among others, and held Visiting Faculty appointments with the Army, NASA, and the Ohio Space Institute. He is 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
