OCC1 622: Community-based occupational therapy

Current research: 

My research primarily focuses on the way communities shape and are shaped by the engagement, inclusion, and occupations of persons who live in or near the margin. Specifically, my team conducts projects on psychosocial rehabilitation, community integration, occupational engagement and recovery of adults who live with mental illness or experience psychosocial challenges, particularly in the areas of housing, homelessness, education and justice involvement. I am leading projet AMONT, a multi-site longitudinal follow-up study examining the housing situation and risk of homelessness among new mental health service users in seven Quebec sites. I am also working extensively with community organizations supporting women and children who experience housing instability. I have a particular interest in building and documenting participatory partnerships where knowledge can be exchanged and co-constructed, particularly around the position of occupational therapy in the field of homelessness, and of intersectoral work of mental health, social services and justice services with and for persons who experience both residential instability and mental illness. I am accepting applications from students interested in pursuing their MSc / PhD in the Graduate Research Program.


Mes travaux de recherche s'articulent autour de la façon dont les communautés soutiennent et sont modelées par l'engagement, l'inclusion, et les occupations des personnes qui vivent dans la marge, ou aux alentours. Plus spécifiquement, mon équipe mènent des projets de recherche sur la réadaptation psychosociale, l’intégration dans la communauté, l'engagement occupationnel et le rétablissement des personnes vivant avec un trouble mental, en particulier celles en situation de précarité comme l’instabilité résidentielle, l’itinérance et l’implication judiciaire. Je mène le projet AMONT, une étude de cohorte longitudinale multi-site visant à examiner la situation résidentielle et le risque d'itinérance chez les personnes nouvellement utilisatrices de services de santé mentale. Je travaille également en collaboration avec les milieux communautaires soutenant les femmes et les enfants en situation d'instabilité résidentielle. Je m'intéresse également à l'échange et à la mobilisation de connaissances, entre autres à l'interface entre ergothérapie et itinérance, ainsi que dans le travail intersectoriel entre pratiques sociales, de santé et judiciaires auprès des personnes itinérantes ayant un trouble mental. Les étudiants intéressés à poursuivre des études de maîtrise ou de doctorat de recherche en réadaptation psychosociale sont invités à communiquer avec moi.
