Biography
Mingsian R. Bai received a B.S. degree in Power Mechanical Engineering from National Tsing Hua University in 1981, and an M.B.A. degree in Business Management from National Chengchi University in 1984. He left Taiwan in 1984 to enter graduate school at Iowa State University, receiving an M.S. in Mechanical Engineering in 1985 and a Ph.D. in Engineering Mechanics and Aerospace Engineering in 1989. In 1989 he joined the Department of Mechanical Engineering of National Chiao-Tung University as an associate professor, becoming a professor in 1996. He moved to National Tsing Hua University in 2010 as a distinguished professor in Power Mechanical Engineering and director of the Telecom-Electroacoustics-Audio (TEA) Laboratory. He was a visiting scholar at the Center of Vibration and Acoustics (Penn State University), the University of Adelaide (Australia), and the Institute of Sound and Vibration Research (ISVR, UK) in 1997, 2000, and 2002, respectively. His research interests span acoustic array systems, audio signal processing, electroacoustic transducers, vibroacoustic diagnostics, and active noise and vibration control, and he serves as a consultant and project leader in these areas in industry. He has published over 275 papers, 6 books (including Engineering Acoustics and Acoustic Array Systems, published by IEEE/Wiley), and 46 granted patents, and has received numerous awards including two Outstanding Research Awards from the National Science Council (2006, 2010). He is a senior member of IEEE, ASME, AES, ASA, the Acoustical Society of Taiwan, and the Vibration and Noise Control Engineering Society in Taiwan. Since July 2012 he has served as an associate editor (transduction and engineering acoustics) and a TCSP member of the Journal of the Acoustical Society of America (JASA), and was a guest editor of the Asian Journal of Control in 2012. He was elected Fellow of the Acoustical Society of America (ASA) in 2014 and Fellow of the American Society of Mechanical Engineers (ASME) in 2021.
