Wei Michael Lai

W. Michael Lai joined the Department of Mechanical Engineering in 1987 as Professor of Mechanical Engineering and Orthopaedic Bioengineering - a joint appointment between the Department of Mechanical Engineering, School of Engineering and Applied Science and the Department of Orthopaedic Surgery, College of Physicians and Surgeons. He served as Chairman of the Mechanical Engineering Department from 1996 to 2002. His research interest is in the area of Orthopaedic Biomechanics.

He is active in the Bioengineering Division of the American Society of Mechanical Engineers (ASME). He served as Chairman of the Bioengineering Division in 1996/97 and an associate editor of the Journal of Biomechanical Engineering, ASME from 1990 to 1996. Among the awards that he has received include two best paper awards for his research in Biomechanics - the ASME Melville Medal in 1982 and the Bioengineering Division Best Paper Award in 1991 and the ASME Lissner Award for outstanding achievement in Bioengineering in 2001. He is a Fellow of ASME and a Founding Fellow of the American Institute of Medical and Biological Engineering (AIMBE).

He has received two teaching awards, including the Distinguished Faculty Teaching Award from the Columbia Engineering School Alumni Association in 2000.
