Greg originally joined NREL in 1987 and worked in the Solar Thermal Program until 1997. During this time, he demonstrated a new concentrating solar technology and initiated a multiyear collaboration with Coors Ceramics Company to develop a high-temperature materials synthesis process. He was awarded three patents for this work.
From 1997 to 2007, Greg operated an R&D small business in which he developed fluid compressor designs and feedback control mechanisms for space applications. This work was funded with several R&D grants from NASA and the U.S. Air Force. He was awarded one patent for this work.
In 2007, Greg rejoined NREL and the Concentrating Solar Power (CSP) team to work on systems analysis, novel heat-transfer fluids, and thermal-storage concepts for CSP technologies. He currently manages the advanced heat-transfer fluids and thermal-storage work at NREL.
