Matthew Thornton joined NREL in 2000 and today serves as a strategic program manager in the Energy Conversion and Storage Systems Center. In conjunction with his NREL position, he is an affiliate professor at Colorado State University and an adjunct professor at the Colorado School of Mines, where he teaches a course he developed on transportation, energy, and the environment.

Previously he managed NREL’s fuels and combustion science group, which conducts cross-cutting research spanning from individual molecules to vehicle-scale fuel economy and emissions performance. He also served as NREL’s principal investigator for the U.S. Department of Energy’s Hydrogen Storage Engineering Center of Excellence, advancing materials-based hydrogen storage systems for fuel cell vehicles, and oversaw NREL’s Renewable Fuels and Lubricants Lab.
