Deborah Da Costa is a scientist at the Research Institute, McGill University Health Centre and an associate professor in the Department of Medicine, Faculty of Medicine at McGill University. Her research focuses on the interplay between modifiable psychosocial and behavioural (e.g. exercise) factors and health status in various chronic illnesses and in relation to depression in populations at risk. This has laid the foundation for the knowledge-transfer phase of her program which focuses on tailoring and evaluating evidence-based e-health interventions to empower individuals with the knowledge and skills needed to optimize their health and wellness.
