Research Interests

Human musculoskeletal modeling and development of control systems for rehabilitation of individuals with spinal cord injury and other balance disorders. Design of rehabilitation devices for physically challenged individuals. My research interests is in the area of musculoskeletal computer modeling and its applications to human locomotion. I develop and solve large scale dynamic and static optimization problems that arise in the study of human locomotion. These include applications to the control of human bipedal standing and also control of seated postures for individuals with spinal cord injury and other balance disorders. The models I develop help other researchers and clinicians to resolve issues and get insight about the workings of the intact human central nervous system. The idea is to get as much information as possible without having to resort to time-consuming and often dangerous experiments with human subjects. I also contribute to projects involving the design of rehabilitation devices for physically challenged individuals.

Teaching Interests

Biomechanics of human locomotion, dynamics of multi-body systems, static and dynamic optimization, control theory and applications.
