Qollab is a research lab located at Qollab is a research lab located at l’École de santé publique de l’Université de Montréal and affiliated with the Centre de recherche en santé publique (CReSP). Our goal is to work in collaboration with 2S/LGBTQIA+ communities to describe and understand health issues, with a focus on identifying the social, contextual, and structural factors underlying health problems. We are particularly interested in mental health and substance use in 2S/LGBTQIA+ communities. We generate high quality evidence to inform the development and implementation of health promotion policies and interventions.

Our research activities focus on two axes

Advance understanding of the lived experience of mental health and substance use among 2S/LGBTQIA+ to identify interventions grounded in 2S/LGBTQIA+ lived experiences.
