Scholarly Activity
My primary research area is in both motor control and biomechanics, focusing on elderly population and minorities. It includes fall prevention in aging, rehabilitation, and intervention. I am interested in studying the mechanism of human balance control, locomotion and developed training program for community-dwelling older adults, and currently extending this research in minority populations. My second research area is focusing on motor learning in human performance. It includes skill acquisition, medical education, simulation technology and telemedicine.
