Karl Orishimo, MS

Research Associate/Biomechanist

Karl Orishimo received his Bachelor’s Degree in Bioengineering from the University of Pennsylvania (1998) and his Master’s Degree in Biomedical Engineering from the University of Virginia (2000). In 2010, Karl also earned his Certification as a Strength and Conditioning Specialist (CSCS). From 2000 to 2003, Karl was a research associate/engineer at the Anderson Orthopedic Research Institute where he studied clinical and biomechanical factors related to the wear of total joint replacements.

Since 2003, Karl has been a Biomechanist and Research Associate at the Nicholas Institute of Sports Medicine and Athletic Trauma [NISMAT] at Lenox Hill Hospital in New York City, working with a multidisciplinary research team. His expertise is in biomechanics, human performance and in the application of engineering principles to problems in biomedicine.

Among his research interests and areas in which he has published are the analysis of human motion, injury biomechanics, and testing of implants and surgical techniques. Karl is a member of the American College of Sports Medicine, the American Society of Biomechanics, the International Society of Biomechanics and the National Strength and Conditioning Association. He has served as a reviewer for Clinical Biomechanics and Human Movement Science and since 2006, he has been an Adjunct Associate Professor of Mechanical Engineering at The Cooper Union.
