Dr. Hull is a biomechanical engineer with expertise in orthopaedic biomechanics and musculoskeletal modeling and simulation of movement. Over the past 15 years, his research has focused on developing improved surgical procedures for treating knee injury and disease and specifically treating end-stage osteoarthritis using total knee arthroplasty (TKA). Since one goal of TKA is to restore function, he also develops new and improved methods including sensors and computational procedures for quantifying biomechanical variables such as kinematics and contact forces that characterize function of the tibiofemoral and patellofemoral joints.
