Yuan-Shin Lee serves as the Director of the Smart Manufacturing Innovation Center (SMIC) at NC State University, funded by the Department of Energy (DOE). The SMIC Center is to link manufacturers, industrial technology vendors, systems integrators and equipment providers with academia, demonstrating and driving research and innovation that scales to all of US manufacturing.

Lee has been a professor of Industrial and Systems Engineering at NC State University since 1995. He is a registered professional engineer (PE) in mechanical engineering. He is also a certified manufacturing engineer in system integration and control. Dr. Lee received the National Science Foundation (NSF) CAREER Award. He also received the 1997 Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers (SME), the 1998 Norman Dudley Award from the Taylor & Francis Journals, London, U.K., the 1999 C.A. Anderson Outstanding Faculty Award, the 2000 Alumni Faculty Outstanding Teaching Award from NC State University, the 2001 ALCOA Foundation Engineering Research Achievement Award, the 2006 Technical Innovation Award from IIE, the 2007 IIE Fellow Award, the 2008 ASME Fellow Award, and the 2012 CAD Best Paper Award.

Lee is a Fellow of the Institute of Industrial Engineers (IIE) and a Fellow of the American Society of Mechanical Engineers (ASME). Dr. Lee earlier served as a Department Editor for IIE Transactions, and an Associate Editor for the Journal of Computer-Aided Design and Applications, the International Journal of Mechtronics and Manufacturing Systems (IJMMS), the Journal of Manufacturing Systems (JMS), the International Journal of Industrial and Systems Engineering (IJISE), and the Journal of Computer-Aided Drafting, Design and Manufacturing (CADDM).

Lee is also an FAA certified private pilot. He flies single-engine land-based airplanes.
