Professor Klein is currently an Emeritus Professor of Mechanical Engineering at University of Wisconsin – Madison. He received his Ph.D degree in Chemical Engineering at University of Wisconsin – Madison in 1976 and he has been on the faculty at Wisconsin since 1977, associated with the Solar Energy Laboratory. He is the author or co-author of more than 160 publications relating to energy systems and the co-author (with Professor Greg Nellis) of recent books in Heat Transfer and Thermodynamics published by Cambridge University Press. Professor Klein’s current research interests are in thermodynamics, refrigeration, and solar energy applications. In addition, he has also actively involved in the development of engineering computer tools for both instruction and research. He is the primary author of the TRNSYS (TRaNsient SYSytem) simulation program that is widely used for solar energy system studies. He also is the author of a finite element heat transfer program, FEHT, and the general engineering equation solving program, EES. Professor Klein is a Fellow of the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE), the American Society of Mechanical Engineers (ASME), the American Solar Energy Society (ASES), and the International Building Performance Simulation Association (IBPSA).
Professor Klein is retired and no longer accepting graduate students.
