Frank Kreith is a professor emeritus of engineering at the University of Colorado at Boulder, where he taught in the Mechanical and Chemical Engineering Departments from 1959 to 1978. For the past 13 years, Dr. Kreith served as the American Society of Mechanical Engineers (ASME) legislative fellow at the National Conference of State Legislatives (NCSL), where he provided assistance on waste management, transportation, and energy issues to legislators in state governments. Prior to joining NCSL in 1988, Dr. Kreith was chief of thermal research at the Solar Energy Research Institute (SERI), now the National Renewable Energy Laboratory (NREL). During his tenure at SERI, he participated in the presidential domestic energy review and served as an advisor to the governor of Colorado. In 1983, he received SERI's first General Achievement Award. He has written more than a hundred peer-reviewed articles and authored or edited 12 books.
Dr. Kreith has served as a consultant and advisor all over the world. His assignments included consultancies to Vice Presidents Rockefeller and Gore, the U.S. Department of Energy, NATO, the U.S. Agency for National Development, and the United Nations. He is the recipient of numerous national awards, including the Charles Greeley Abbott Award from the American Solar Energy Society and the Max Jakob Award from ASME-AIChE. In 1992, he received the Ralph Coates Roe Medal for providing technical information to legislators about energy conservation, waste management, and environmental protection, and in 1998 he was the recipient of the pretigious Washington Award for "unselfish and preeminent service in advancing human progress."
