Argy Stampas, MD

Dr. Stampas is an early career physician researcher and Site-Principal Investigator at TIRR for research project 2.

As a physician researcher, I want to advance the field of rehabilitation using electric stimulation to prevent problems commonly found in spinal cord injury (SCI), including neurogenic bladder and bowel, autonomic dysreflexia, neuropathic pain, and spasticity. In my position as the SCI Medicine Research Director, I can pursue research interests with the support of TIRR Memorial Hermann, UT Health Science Center at Houston, and their research infrastructure to support high-level clinical research. I am involved in the care of hundreds of SCI patients annually, and the institution serves one of the largest SCI populations in the country.
