Nnamdi Orakpo, MD, PhD
Clinical Assistant Professor, Psychiatry and Behavioral Sciences - Sleep Medicine
BioNnamdi Orakpo's path to becoming a bilingual Sleep Medicine Psychiatrist & Interventional Psychiatrist was far from conventional. Originally, he was focused on a professional basketball career in Australia and New Zealand. However, his father's guidance led him to pursue higher education.
At the University of North Texas, Dr. Orakpo completed a doctorate in Gerontology before attending medical school in Mexico and completing his residency in Psychiatry at Garnet Health Medical Center in New York. He graduated from Sleep Medicine fellowship training at Stanford University, Department of Psychiatry, Division of Sleep Medicine in Sleep Medicine (2023), where he is currently serving as a Clinical Assistant Professor.
Dr. Orakpo has published numerous articles in SLEEP, Frontiers Journal of Psychiatry, Frontiers Journal of Human Neuroscience, Journal of Clinical Sleep Medicine, and has collaborated with Stanford University colleagues on a textbook on clinical sleep medicine, where he authored the chapters on chronic insomnia, isolated sleep paralysis, sleep enuresis, sleep related eating disorder, sexsomnia, and exploding head syndrome. His research and clinical practice have centered around Sleep Medicine and Sleep Psychiatry. He conducted a pioneering study on using Virtual Reality Neurofeedback as a treatment for chronic pain and insomnia. This work was supported by an institutional grant and has contributed to the field of sleep medicine.
Beyond his clinical work, Dr. Orakpo is an active researcher and educator. He recently published and co-authored commentary in the Journal of Clinical Sleep Medicine on pharmacological management of sleep apnea and obesity with GLP-1 medications.
