Career Summary

After completing 2 years of pediatric gastroenterology training, I completed a fellowship studying the effects of probiotics and lactoferrin on the intestinal microbiota of premature infants as well as their effects on an animal mode. Since completing my master’s degree, I have been working full time as a pediatric gastroenterologist at Sainte Justine. I have continued my research on the intestinal microbiome while collaborating with McMaster University and Children’s Hospital of Eastern Ontario, on projects related to the intestinal microbiome of children and adolescents with inflammatory bowel disease.
