Research Interests

Functional Disorders of the Gastrointestinal Tract

Around the world, between 10-17% of school age children have abdominal pain disorders such as functional abdominal pain, irritable bowel syndrome, and dyspepsia. Our goals are to understand the factors contributing to the development of these conditions and to develop effective treatments and management strategies. We are addressing these disorders using a multidisciplinary approach involving collaboration between basic scientists, clinical research scientists, practicing physicians, psychologists, and nurses.

Areas of research we are investigating include the roles of:

a) Diet
b) Maldigestion
c) An altered composition of bacteria in the gut
d) Gut barrier dysfunction
e) Psychosocial distress
f) Alterations in central and peripheral nervous system processing
g) Probiotics, fiber, and other modalities for treatment
