Stephen Masutani is a tenured Researcher in the Hawaii Natural Energy Institute. He was graduated from the University of Hawaii with a B.S. in Mechanical Engineering in1977. He earned his M.S. and Ph.D. in Mechanical Engineering from Stanford University in 1980 and 1985, respectively. In 1985, he joined the Hitachi Research Laboratory of Hitachi, Ltd. in Japan, working at the Coal Technology Center on multiphase flow combustion and the development of optical diagnostics for applications in coal combustors. In 1989, Dr. Masutani returned to Hawaii where he worked at the Pacific International Center for High Technology Research on ocean thermal energy systems and ocean sequestration of CO2, until joining the faculty of the University of Hawaii at Manoa in 1994. His areas of specialty include thermochemistry and kinetics, CO2 sequestration, methane hydrates, deep oil spills, multiphase flows, combustion, and renewable energy systems. His current research focuses on marine methane hydrates (funded by the Office of Naval Research) and deep ocean oil spills (funded by the American Petroleum Institute, Gulf of Mexico Research Initiative, and Chevron-MIT University Partnership Program).
