Research Interests

I have a long-standing interest in chronic gastrointestinal diseases of children, especially celiac disease and inflammatory bowel disease.  We published the first North American studies on the association of type 1 diabetes and celiac disease, results of a national health survey on celiac disease, and the first description of the changing face of celiac disease in North American children.  We have also evaluated how physicians interpret and manage serological tests for celiac disease.  I have created a database of children with celiac disease in Southern Alberta dating back to 1990.  Current studies are using the database to determine which patients require duodenal cap biopsies in order to possibly reduce the number of biopsies required to make a diagnosis of celiac disease.  We are evaluating  guideline recommendations made by the European Society of Pediatric Gastroenterology, published in 2012, that suggest children with very high celiac serology levels do not require an intestinal biopsy.  Both of these projects have the potential to save the health system time and money.


I am involved in the research mentoring of junior members and trainees of the Division of Pediatric Gastroenterology and Nutrition. Thus my focus is on the evaluation of chronic gastrointestinal disease in children as well as mentoring junior faculty and trainees in the Division of Pediatric Gastroenterology and Nutrition.
