About Dr. Wright

Tim Wright is the FM Kirby Chair in Orthopaedic Biomechanics at the Hospital for Special Surgery, Professor of Applied Biomechanics in Orthopaedic Surgery at the Weill Medical College of Cornell University, and a Member of the Graduate Field of Biomedical Engineering at Cornell University in Ithaca, New York. Dr. Wright's research efforts focus on orthopedic implant performance through approaches that include clinical, radiographic, and biomechanical measures and that are integrated across disciplines such as radiology, orthopedic surgery, biomaterials, and biomedical engineering. He has published more than 300 peer-reviewed articles. He has also helped develop implant systems for knee, hip, and elbow replacement that have gone on to commercial distribution to patients worldwide.

Dr. Wright received his undergraduate degree from Lehigh University and his graduate degrees from Stanford, after which he joined HSS. He is a recipient of honors for excellence in research from the Hip Society and the Knee Society and earned a Kappa Delta Award from the American Academy of Orthopedic Surgeons for outstanding musculoskeletal research. Dr. Wright received a Director's Special Citation from the U.S. Food and Drug Administration for his work on a forum of academic, industry, and FDA representatives striving to improve the regulatory process for orthopedic devices. A past Whitaker Fellow and past recipient of a Research Career Development Award from the NIH, Dr. Wright served as president of the Orthopedic Research Society in 1992. He was the Program Director on an NIH-funded musculoskeletal research training grant at HSS for ten years and served as the first Director of the Hospital's NIH-sponsored Core Center for Skeletal Integrity. He is currently the Coordinating Program Director of the NIH-funded Clinical and Translational Science Center at Weill Cornell. Dr. Wright is a former consulting editor for research of the Journal of Bone and Joint Surgery and was co-editor of the Journal of Orthopaedic Research for 18 years. He is a Fellow of the American Institute for Medical and Biological Engineering and a recipient of the Alfred Shands Award from the Orthopaedic Research Society for significant lifetime contributions to orthopedics.


Improving orthopedic implant performance through approaches that include implant retrieval analysis, computational models of implant fixation and joint kinematics and multidisciplinary approaches that combine biomechanics with clinical, radiographic, and pathological measures.

Preventing traumatic arthritis through studies of joint mechanobiology and contact mechanics aimed at identifying loading regimes and biological treatments that can mitigate joint degradation.
