For the past 30 years the focus of my academic activities has been the diagnosis and treatment of functional and motility disorders in children of any age. I have pioneered the use of manometry and barostat testing to evaluate motor and sensory function in the upper and lower GI tract. I have held leadership positions within NASPGHAN, ANMS, AGA, Brain-Gut Club, and ABP. I have chaired both the Rome III and Rome IV Child-Adolescent committees and I have had more than 280 peer-reviewed and invited manuscripts in the field of functional and motility disorders in pediatrics. I was awarded the Master Award in Gastroenterology by the AGA. I was the President of NASPGHAN from 2014 to 2016.

His research interests in the field of neurogastroenterology/motility have focused on gaining mechanistic insights, developing novel diagnostic tools and pioneering innovative treatments for common disorders especially constipation, dyssynergic defecation, fecal incontinence, IBS, food intolerance, gas and bloating, small intestinal bacterial and fungal overgrowth (SIBO/SIFO) and visceral pain. He is credited with discovering dyssynergic defecation, a problem that affects one-third of constipated patients and its remedy, biofeedback therapy, as well as novel treatments and sensory adaptation training for rectal hypersensitivity. He has pioneered several novel tests, translumbosacral anorectal magnetic stimulation for pelvic floor neuropathy, esophageal balloon distension for chest pain, and fructose and fructan breath tests.
