Originally from Bayfield, Ontario, Keller is a professor in the Department of Kinesiology at Waterloo. She earned her BASc in applied nutrition from the University of Guelph, and an MSc in nutrition from McGill. She earned a Doctor of Philosophy in epidemiology and biostatistics at Western University, and worked as a faculty member in the Department of Family Relations and Applied Nutrition at the University of Guelph before joining Waterloo. Her research has appeared in several key publications and peer-reviewed journals. She currently serves on the editorial board for the Journal for Nutrition, Gerontology and Geriatrics, Journal of Aging Research Journal of the American Medical Directors Association and the Canadian Journal of Dietetic Practice and Research.

Part of Keller’s research focuses on diet resilience and nutrition risk. These terms refer to people’s ability to maintain a healthy diet and appetite through life’s challenges, and their changing nutritional needs as they age.

“Roughly 30 to 40 per cent of people over the age of 65 have some level of nutrition risk. If we don’t fix this issue, it can lead to malnourishment,” she said. “Aside from eating food with enough nutrients, the ability to get to a store to shop or to carry groceries can also affect food intake for seniors.”
