Principal Investigator: Yi-Ting Tzen, PhD

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

Dr. Tzen’s research theme revolves around pressure injury and diabetic foot ulcer risk identification and prevention. Dr. Tzen utilizes non-invasive skin blood flow measurement to quantify severity of tissue ischemia and microvascular dysfunction. She investigated effectiveness of local cooling and alternating pressure on enhancing tissue tolerance toward pressure in people with spinal cord injury, and changes in microvascular function in trauma patients with spinal cord injury and people with type 2 diabetes. She currently expanded her research to include energy metabolism as a modifiable predictor for chronic wound formation.
