What We Do

The Presseau Group is multidisciplinary team of research staff and trainees focused on rigorously drawing from - and contributing to - behavioural and implementation science to support the health and well-being of patients, the public, and supporting health providers in the health care system to provide high quality care. We do so in partnership with interest holders including patients, people with lived experience and health system decision makers and health providers, and with a strong commitment to equity-focused research.

Our team draws upon multiple methodological approaches (e.g., evidence syntheses, qualitative methods, priority-setting methods, surveys, and randomized trials), spanning a number of different clinical areas including chronic disease, blood and tissue, infectious diseases and personalized health. Further, we are committed to developing theory, methods and evidence in conceptually novel areas including building and rebuilding trust, the effectiveness of implementation intentions for behaviour change, strategies for addressing mis/disinformation, understanding and supporting sustained change, and moving from single to multiple behaviour change approaches. 

We support multidisciplinary training opportunities including undergraduate, graduate and post-doctoral supervision through affiliations with the University of Ottawa School of Epidemiology and Public Health and School of Psychology, as well summer studentships and practicum placements.
