Research Interests

Biomechanical engineering applications in orthopaedics with emphasis on total joint replacement of the knee. In vitro and in vivo study of biomechanical variables which affect knee function following total joint replacement including the use of advanced techniques in biomedical imaging. Design of implants to optimize knee function in total joint replacement. Design of novel sensors to measure contact loads, relative bone motions in 3D, and soft tissue strains in the study of knee function.
