My research focuses on methodological approaches to studying early childhood health using clinical and screening databases linked to ICES health administrative data. With Dr. Kumanan Wilson, I helped develop VISION (Vaccine and Immunization Surveillance in Ontario), an analytical infrastructure for conducting studies of vaccine safety using Ontario health administrative data. I am currently working with Ontario newborn screening metabolite data and BORN perinatal data coupled with ICES health administrative data to answer important health questions, such as predicting health outcomes in childhood, and whether gestational age, low birthweight as well as perinatal stressors and birth complications result in identifiable patterns and signals in screening metabolite data at birth.
