George A. Tsianos

Senior Consultant / Ph.D. / San Diego


Dr. Tsianos received a Ph.D. in Biomedical Engineering, an M.S. in Mechanical Engineering, and an M.S. in Medical Devices and Diagnostics Engineering from the University of Southern California.  Dr. Tsianos’ primary areas of consulting expertise include vehicle accident reconstruction, injury causation biomechanics, general biomechanical analysis, medical device design, testing, and failure analysis, physical rehabilitation, prosthetics and robotics. Dr. Tsianos has a long track record of research in musculoskeletal mechanics, neural control of movement, and prosthetics for restoring patients’ abilities to perform activities of daily living. Dr. Tsianos has applied basic research including his own for predicting, enhancing, and restoring physical performance for many subject populations such as patients with movement disorders, elite athletes, and military personnel.

Dr. Tsianos’ prior experience includes basic research in musculoskeletal and nervous system physiology that have provided fundamental scientific advancements. Notable accomplishments include the first and only validated method for predicting caloric expenditure of skeletal muscles and the most comprehensive computational model of the neural network in the spinal cord that mediates movement.  He has also developed software tools for sharing this knowledge and applying it toward understanding and predicting physical performance and musculoskeletal injury. Dr. Tsianos also has experience with developing a motion tracker for obtaining commands to control upper limb prosthetics and paralyzed muscles. His collective experience has enabled him to consult with many researchers on predicting physical performance decrement and musculoskeletal injury (acute and chronic) for a wide range of scenarios including normal exercise as well as accidents such as blast and crashes.
