What I do
My research utilizes novel methodologies for measuring and simulating musculoskeletal injury and treatment. There is no practical or ethical way to measure the forces, stresses, and strains that occur inside the human body during activities of daily living, work, and sport. Musculoskeletal modeling and simulation enables estimation and prediction of the demand on tissues during activity. This information allows the investigation of treatments designed to address orthopedic pathology and prevent injury. Musculoskeletal modeling is a predictive computer simulation approach that relies on detailed representation of the bones, muscles, and ligament anatomy. My current work is supported by the National Institutes of Health and industry sponsors, and focuses on the development and demonstration of a multi-scale musculoskeletal models of the human body that are capable of realistic simulation of dynamic physical activity and applied to current issues in total joint replacement. This initiative fills a broad need in medical research for more realistic representation of the human tissues in simulation. My research is also focused on the development and use of biplane fluoroscopy. Biplane fluoroscopy is a stereo x-ray technique that provides very accurate 3D tracking of bones and implants during dynamic activity. Using biplane fluoroscopy, the small relative motions of the bones of the joints of the human body can be measured. Not only does this provide a surrogate measure of the demand on the muscles and soft tissues, it is also the only method of obtaining measurements at the millimeter scale of soft tissue injury and repair.
