Krista A. Power

Krista Power is an associate professor at the School of Nutrition Sciences, University of Ottawa, and an adjunct professor at both the Department of Human Health and Nutritional Sciences, University of Guelph, and the Department of Nutritional Sciences, University of Toronto. In 2007, she earned a PhD from the Department of Nutritional Sciences, University of Toronto, and from 2006 to 2008, she was an NSERC post-doctoral fellow at the University of Turku, Finland, and at the Karolinska Institute, Stockholm, Sweden, during which she used an array of cellular and in vivo models to research the role of phytoestrogens and phytoestrogen-rich foods, such as flaxseed and soy, on estrogen signalling in human health and disease.

From 2008 to 2017, Professor Power served as a research scientist with Agriculture and Agri-food Canada, where she initiated and led a diet-and-gut health research team in demonstrating the importance of dietary components in modulating the intestinal microbiota and in intestinal barrier integrity and function, and the role of diet in preventing and treating chronic disease.

Professor Power is accepting new students for thesis supervision.
