Research interests

My research focuses on cognitive and attentional processes involved in multiple-task performance in adulthood and healthy aging. I am interested in studying situations in which multiple tasks are either carried out in sequential order, or are performed concurrently. A portion of my current work investigates the coordination of cognitive and motor tasks in old age (e.g., walking, balance, finger sequencing, with a concurrent cognitive load). An important theme in my research is to understand the adaptive strategies that older adults develop in response to declines in cognitive and sensorimotor abilities. I am a member of the Centre for Research in Human Development (CRDH), which is devoted to multidisciplinary approaches to the study of development across all life periods. I am also a member of the PERFORM Centre for preventive health research. Graduate students working with me participate in regular workshops and seminars offered by both organizations.
