Jacob Leachman is an Associate Professor in the School of Mechanical and Materials Engineering at Washington State University (WSU). He initiated the Hydrogen Properties for Energy Research (HYPER) laboratory at WSU in 2010 with the intent to advance the Technology Readiness Level (TRL) of cryogenic hydrogen systems. He earned a B.S. degree in Mechanical Engineering in 2005 and a M.S. degree in 2007 from the University of Idaho. His master’s thesis has been adopted as the foundation for hydrogen fueling standards and custody exchange, in addition to winning the Western Association of Graduate Schools Distinguished Thesis Award for 2008. He completed his Ph.D. in the Cryogenic Engineering Laboratory at the University of Wisconsin-Madison in 2010 under the advice of John Pfotenhauer and Greg Nellis. He is the lead author of the reference text “Thermodynamic Properties of Cryogenic Fluids: 2nd Edition”. In 2018 he received the Roger W. Boom Award from the Cryogenics Society of America.
