Current Research Projects

My research investigates the social epidemiology of sexual health, including the spatial movement of diseases and ideas through social/sexual networks. My ideas emerge from a transformative, relational paradigm. I use mixed methods to investigate sexual health as a complex system, with connections to physical, mental, emotional, spiritual, and social health. The projects I am involved with are often community based and consider culture. I have worked with Indigenous, marginalized, and hard-to-reach communities, as well as the general population, to develop effective interventions that transform sexual health at individual, community, and provincial levels.
