In 2015, the World Health Organization identified antibiotic resistance as a threat at the very heart of modern medicine, enjoining member countries to take action in a multi-sectoral “One health” approach. So, in addition to wildlife, water and soil, which have already been the focus of a number of research projects, we'd like to study a dispersal pathway that has never been explored before: air. Indeed, air can contain microorganisms from different sources and transport them over very long distances. The Canada Research Chair in Bioaerosols team is trying to understand how air acts as a vehicle for microorganisms, and is working to develop models that can guide public policy.
