Glenn Grant’s research focus is on developing new advanced manufacturing processes and new materials to decrease the embedded energy in manufacturing and to deploy products that allow new levels of energy efficient operation. He currently leads a portfolio of projects and programs investigating Solid Phase Processing as a new manufacturing technology. Over the course of his tenure at PNNL, Mr. Grant has initiated and developed a division level focus on Solid Phase Processing. The program includes research work on material processing and advanced manufacturing process development projects across DOE and Industrial sponsor space. He has co-developed a Laboratory Initiative on the fundamental science of Solid Phase Processing and led one of the two Thrust areas of the initiative. Currently Mr. Grant leads the DOE EERE VTO sponsored Core Research Program on Light Weight Materials (LMCP). Mr. Grant currently holds 13 US Patents, with an additional 4 patents pending. He has been recognized as a key contributor in licensing activities at PNNL and has been awarded 2 R&D 100 Awards on technologies associated with Solid Phase Processing.
