Dr. Tzen's research interest is early detection of pressure injury in people with spinal cord injury using non-invasive perfusion markers and serum biomarkers, and wound prevention through assistive technology devices. Dr. Tzen had clinical training in Physical Therapy and Assistive Technology, and technology training in bioinstrumentation and signal processing.
