A professor emeritus at the Université de Montréal, she has developed numerous courses and was the first holder of the Research Chair in Nursing Care for Seniors and Their Families. In the tangible application of her research findings, she brought about major changes in nursing practices in Canada and elsewhere. In particular, she made an impact on the care of Alzheimer's patients and on the support given to their caregivers. Her book, Alzheimer, comprendre pour mieux aider, remains a key reference in the field. She is also a sought-after speaker and a researcher at the Centre de recherche de l'Institut universitaire de gériatrie de Montréal.
