Meet the people who have contributed to the research and work of the Translational Musculoskeletal Research (TMSKR) Laboratory.


Principal Investigator


As a clinician-scientist, Dr. Jayabalan aims to find innovative solutions to clinical problems in the research lab. His research uses biomarker analyses (from urine and/or blood) to develop efficacious exercise regimens for people with musculoskeletal injury or disease. This fits into the future concept of individualized and personalized medicine, using individuals' biological profiles to find an appropriate exercise program for them.
