Rao is the founding director of the Digestive Health Center, and the Digestive Health Clinical Research Center and Director, Neurogastroenterology/Motility at Augusta University Medical Center and as a Professor of Medicine (Tenure) at the Augusta University. He served the Chief of the Division of Gastroenterology, Director, GI Service Line, and Fellowship Program Director. Before that, he was a Professor of Medicine and Director of Neurogastroenterology and GI motility and biofeedback program at the University of Iowa Carver College of Medicine, Iowa City, IA.[5]
His research interests in the field of Neurogastroenterology/Motility have focused on gaining mechanistic insights, developing novel diagnostic tools and treatments for common motility disorders especially constipation with dyssynergic defecation, fecal incontinence, IBS, food intolerance notably fructose and fructan, gas and bloating and small intestinal bacterial and fungal overgrowth (SIBO/SIFO) and visceral pain.[6][7][8]
He is credited with identifying dyssynergic defecation, a problem that affects 1/3 of constipated patients and for developing its remedy, biofeedback therapy as well as new treatments, sensory adaptation training for rectal hypersensitivity.[9][10][11] He has pioneered several novel tests, translumbosacral anorectal magnetic stimulation for pelvic floor neuropathy, esophageal balloon distension for chest pain, fructose and fructan breath tests, and treatments such as home biofeedback for dyssynergia and translumbosacral neuromodulation therapy for fecal incontinence and bowel problems.[12][13][14] He developed the first method for examining the bi-directional gut and brain axis in humans.[15][16][17]
He has been awarded 4 patents.[18][19] He is a federally funded principal investigator for 20 years and currently holds NIH UO-1 and RO-1 grants.[20] Dr. Rao has edited 10 books, including Handbook of GI Motility (2015), and Clinical and Basic Neurogastroenterology & Motility (2020).[21] He has published over 500 peer-reviewed articles with 20,500 citations, and an h-index of 82 and ilo index of 225.[22] He has been awarded 3 copyrights for patient-reported symptom diaries and digital Apps for fecal incontinence, constipation and gas/bloating. An astute clinician, Dr. Rao has been selected as one of the “Best Doctors in America” and as Americas’ Top Doctors for over 25 years. He has been invited to lecture in 35 countries as visiting professor. These include live demonstrations and workshops on anorectal manometry, esophageal manometry, and biofeedback therapy and novel TNT procedures, and to train peers globally.
