About Me
In pediatric gastroenterology, we see children of all ages with disorders of the gastrointestinal tract. This can include disorders of the esophagus (food tube), stomach, pancreas, liver, gall bladder, small intestine, large intestine, and rectum. I have a particular interest in caring for children with disorders of gut-brain interaction (DGBI), such as irritable bowel syndrome and functional dyspepsia. DGBI in children may be associated with chronic abdominal pain and meal-related symptoms. I also have a particular interest in caring for children with motility disorders. These include disorders such as esophageal achalasia, gastroparesis, intestinal pseudo-obstruction, and severe constipation. Pediatric gastroenterologists at Duke collaborate with several specialty colleagues in areas such as pediatric surgery, physical therapy, psychology, otolaryngology, and pulmonology to provide cutting-edge clinical care. We also educate pediatric gastroenterology trainees and lead academic innovation through quality initiatives and research to improve pediatric digestive health.

Clinical Focus and Research
There are two primary research interests that I have. The first is research to understand the interaction between diet, such as fermentable sugars, and the gut microbiome to cause gastrointestinal symptoms, such as abdominal pain, in children with irritable bowel syndrome. The second area of research is in pediatric gastroparesis through the NIH/NIDDK-supported Gastroparesis Clinical Research Consortium.
