Introduction
My research is in clinical movement disorders with a focus on diabetic foot ulcer prevention and gait impairment in diabetes. In diabetic foot research, I particularly work with novel digital technologies and apply other interventions including exercise for reducing diabetic foot ulcer risk and improving gait and balance in diabetes.
