Jonghyun Lee is an assistant professor in the Department of Mechanical Engineering at Iowa State University. He has been conducting multiple projects funded by NASA, The U.S. Army Research Laboratory, Iowa Department of Transportation, and Boston Metal in the field of materials processing and manufacturing. Lee is the recipient of the Young Leader Professional Development Award in 2013 from The Minerals, Metals and Materials Society where he has been serving as an organizer and editor of the Materials Processing Fundamentals Symposium and as the chair of the Process Modeling and Technology Committee. Prior to joining the current institution, Dr. Lee was a research assistant professor in the Department of Mechanical and Industrial Engineering at the University of Massachusetts Amherst and a postdoctoral associate in the Department of Mechanical Engineering at Tufts University, Medford, MA. Dr. Lee also had 4.5 years of industry experience, where he worked as an internal consultant providing technical consulting services to design, manufacturing, and field engineers on materials selection, design optimization, troubleshooting during manufacturing, and failure analysis.
