Dr. Lee started his career by joining the Department of Veterans Affairs and University of California, Irvine in 1987 and established an Orthopaedic Biomechanics Laboratory based at the VA Long Beach Healthcare System. Dr. Lee held a rank of Professor Step VI and served as the Vice-Chair for Research and Academic Affairs in the Department of Orthopedic Surgery at University of California, Irvine. He also held a title of Senior Research Career Scientist with the Department of Veterans Affairs RR&D which is the highest honor bestowed to a scientist in the VA system. After 30 years in Academics, Dr. Lee moved his entire staff and laboratory to Pasadena, California to join Congress Medical Foundation. Dr. Lee is continuing his work in orthopaedic biomechanics while focusing on innovation and education according to academic standards. Dr. Lee serves a leadership role in many professional societies and organizations. He is a scientific member in the American Shoulder and Elbow Surgeons (ASES) currently serving as Chair of the Research Committee. Dr. Lee serves as the Deputy Editor for Basic Science for the Journal of Shoulder and Elbow Surgery and an International Editor for the Clinics in Orthopaedic Surgery. In engineering, Dr. Lee was elected to a Fellow for the American Society of Mechanical Engineers (ASME) in 2002. This is the highest distinction that the American Society of Mechanical Engineers awards in recognition for significant and notable contributions made to the field of mechanical engineering. Furthermore, he was also elected to a Fellow by the American Institute for Medicine and Biological Engineering (AIMBE) in recognition of outstanding contribution to the field of medical and biological engineering in 2003. Dr. Lee also served in numerous government and non-profit organizations as a Grant Reviewer including the VA Rehabilitation Merit Review, the NIH, the Extremity War Trauma Foundation/ Airlift Foundation, the Swiss National Science Foundation, and the National Sciences Engineering Research Panel. The primary contribution of Dr. Lee has been the development of research methods and models to biomechanically evaluate shoulder and other joints. Dr. Lee has published over 300 peer reviewed manuscripts and over 500 abstracts in orthopaedic biomechanics. He continues to lecture widely both nationally and internationally.https://pubmed.ncbi.nlm.nih.gov/?term=lee%20tq&sort=datehttps://scholar.google.com/citations?user=ukQ7bg8AAAAJ&hl=en
