Pediatric Gastrointestinal (GI) Motility Disorders

My key interests include gastroparesis, gastric electric stimulation, Intestinal pseudoobstruction, swallowing disorders, constipation, cecostomy, sacral nerve stimulation, rumination, gastroesophageal reflux, Hirschsprung's disease, gastrointestinal motility diseases, rumination, and other functional disorders. I have special clinical expertise in managing patients in multidisciplinary settings and had an active role in developing both aerodigestive and colorectal multidisciplinary teams.
Since my pediatric GI fellowship training at Children’s Hospital of Pittsburgh, my clinical and research activities have been focused on motility and functional gastrointestinal (GI) disorders. In my prospective clinical trials, I evaluated GI physiology as well as investigated the pathophysiology of functional GI disorders, specifically the changes in gastric accommodation and compliance after fundoplication, and clinical outcomes after gastric electric stimulation and sacral nerve stimulation. I pioneered the gastric electric stimulation in pediatrics at Nationwide Children’s Hospital in collaboration with our pediatric surgeon and the motility team. We just reported the 10-year experience in pediatric gastric electric stimulation. Most recently, I have pioneered in applying Body Surface Gastric Mapping (BSGM) to pediatric clinical research at CHOP.
