Ph.D. in Mechanical Engineering, University of Illinois, 1995
Dr. Heun graduated from Calvin with a BSE in 1989. He completed is M.S. in Mechanical Engineering in 1990 and finished his Ph.D. in 1995, both at the University of Illinois. During that time, he worked as a research assistant in the Air Conditioning and Refrigeration Center (ACRC) at the University of Illinois. His work at the ACRC focused on the optimization of heat exchangers using ozone-friendly refrigerants.
After completing his Ph.D., Dr. Heun worked at NASA’s Jet Propulsion Laboratory (JPL), Pasadena, CA, where he led studies and experiments related to planetary exploration with balloon systems. After working at JPL, Dr. Heun joined Global Aerospace Corporation (GAC), a start-up aerospace R&D company, as its first full-time employee. At GAC, Dr. Heun proposed, led, and completed several projects in support of NASA’s Earth Science activities. Dr. Heun spent his 2009 sabbatical in South Africa at the Centre for Renewable and Sustainable Energy Studies and the Cape Peninsula University of Technology where he taught and participated in sustainable energy development.
