Yishi Lee

Associate Professor of Mechanical Engineering

Engineering and Engineering Technology

Biography

Yishi Lee received his BS and MS degrees in physics from Embry-Riddle Aeronautical University in 2007 and 2013, and the Ph.D. degree in Mechatronic Engineering from the University of Denver in 2020. He is currently an Assistant Professor with the Engineering and Engineering Technology Department, Metropolitan State University of Denver, Denver, CO, USA. He is also working with an industry partner specializing in ultrasonic-based stress waves for nondestructive evaluation in wooden utility poles, leading the firm in research and development and algorithmic developments. The resultant features are used for condition characterization and advance the NDE technology. His collaborative efforts with multiple government agencies, academic institutions, and private firms have helped produce numerous journal articles, conference papers, and commercial patents. His research focuses on advancing the applications of ultrasonic signal processing and analysis based on physical principles.
