My Biography & Research


I was influenced by my father, who was a pediatrician and took great satisfaction in caring for children. As a pediatric infectious disease specialist, I work with my patients and their families as a team and feel that taking care of children is a wonderful privilege and a responsibility.

In my practice, I try to be flexible by coordinating my patients’ appointments with those of other providers when possible. I’m committed to providing continuity and to being accessible between visits.

I’m the director of the Antimicrobial Stewardship Program and the Microbial Genomics and Metagenomics Laboratory. I've received several teaching and research awards, including the Pediatric Infectious Disease Society Young Investigator Award.

The main focus of my research is on the microbiome, which is the community of bacteria, viruses, fungi and other organisms that live on the human body. The goal is to understand how the microbiome influences disease and contributes to health in children. A healthy microbiome helps protect against infection, allergy, gastrointestinal diseases, heart disease, diabetes and diseases of premature infants.

In my free time, I enjoy riding my bike.
