Anita Kozyrskyj is professor of pediatrics at the University of Alberta, Canada. She leads the SyMBIOTA research program on environmental shaping of the infant gut microbiome, and development of child overweight and atopic disease in the CHILD Cohort Study. SyMBIOTA was funded by one of seven team grants from the 2010 CIHR Microbiome Initiative and is now part of 2019 CIHR IMPACTT microbiome research network. Prof. Kozyrskyj’s SyMBIOTA program has generated 55 papers and two book chapters. One of these papers was a first report on the impact of household cleaning products on infant gut microbiota. Her other papers have received awards for being the most influential publication and were presented to policy makers such as the US National Academies of Sciences, Engineering, and Medicine Committee on Food Allergy. She is associate editor of Journal of Developmental Origins of Health and Disease and was co-editor of the 2016 special issue on “The Gut Microbiome and Immunity: How it is Shaped in Early Life.” She is on the executive board of the inVIVO Planetary Health network.
