- Muscle mechanics: cardiac & skeletal muscle mechanics; titin
- Musculoskeletal health: Patellofemoral joint mechanics; knee joint pain; quadriceps muscle imbalance
Dr. Seong-won Han has two areas of research. First is the study of titin, a molecular spring connecting myosin filament and Z-line in a sarcomere. Her primary research goal is to investigate the exact role of titin and how it contributes to muscle contraction. This is achieved using both cardiac and skeletal muscle at cellular and sub-cellular levels.
The second area of research Dr. Han is interested in is patellofemoral joint mechanics associated to quadriceps muscle imbalance using animal models. She measures changes in mechanical properties of the patellofemoral joint (i.e. pressure distribution and patellar tracking) when the quadriceps muscle group is activated individually in isolation. This research allows her to quantify how individual quadricep muscles contribute to the patellofemoral joint mechanics, and how muscle imbalance in the quadriceps group would change its mechanical properties, and, eventually, how it would be potentially related to patellofemoral pain.
