Dr. Heather Keller, a Professor in the Department of Family Relations and Applied Nutrition at the University of Guelph, is an expert in nutrition and older adults. Through her research, she strives to improve the nutritional state and health of older adults, whether they live in communities or in institutions. Dr. Keller's research program is comprehensive, ranging from screening and the assessment of nutritional states to the evaluation of innovative interventions, food products and programs. She has developed a wide collaborative network for research in both community and clinical settings.

Dr. Keller has three research streams: 1) nutrition risk screening, 2) nutrition and aging well in older adults, and 3) nutrition and dementia. She uses both quantitative and qualitative methods to answer applied research questions. Translating this research and knowledge to practitioners, families, and older adults is a priority.
