Research Focus

My research focuses on the treatment of patients with HIV and chronic hepatitis. As a prominent researcher in clinical and epidemiologic aspects of HIV and Hepatitis C co-infection, I lead one the largest multicenter cohorts focused on HIV/HCV co-infection in the world, recruiting more than one thousand HIV/HCV co-infected patients across Canada. The primary objectives of the CIHR funded cohort are to study the interactions between these two chronic viruses and their natural history in the era of combination antiretroviral therapy (cART) and to evaluate therapeutic strategies aimed at improving health outcomes in co-infected persons. We are also focused on understanding the roles of co-morbidities in the natural history of HIV/HCV co-infection. In addition, I am involved in a number of observational epidemiologic research collaborations (NA-ACCORD and CANOC) that focus on understanding long term clinical and treatment outcomes in HIV infection. My other research interests include antiretroviral pharmacoepidemiology and HIV infection in women.
