Anita Kozyrskyj

I am interested in epidemiological research using population-based birth cohort studies with linkage to existing healthcare databases. My current research interests focus on early life programming of childhood atopic disease and overweight, as influenced by birth method, infant diet and antibiotic use during pregnancy, birth and infancy. I am the principle investigator of SyMBIOTA (Synergy in Microbiota) research program, one of the seven CIHR-funded Canadian Microbiome Initiative teams. The SyMBIOTA program, which derives its data from the 4-site CHILD (Canadian Healthy Infant Longitudinal Development) pregnancy cohort study, aims to investigate pre- and postnatal influences on infant gut microbiota and their connection to the development of atopy and overweight.
