My Biography & Research


Children make the best patients, and I love seeing them get better and thrive. I chose my specialty area due to the variety of my practice. I work with inpatients and outpatients and also perform procedures. Conditions I treat range from very simple to very complex. I am also involved in quality improvement work.

As a pediatric gastroenterologist, I specialize in pediatric inflammatory bowel disease (IBD) and the treatment of C. difficile infection in children. I want the child and the family to thrive. A sick child impacts the entire family, so alleviating the family worry and the burden of the disease is important to me. Our IBD team is amazing and driven, and our nurses are second to none.

My clinical research centers on the impact of the microbiome in IBD. I also study patterns and processes in care that can be optimized to improve patient outcomes (quality improvement).

When I’m not helping patients, I enjoy spending time with my husband and children more than anything. I also like cooking, ballet and crossword puzzles. I studied Japanese for many years, but I'm pretty rusty!
