Liam has worked as a streetworker (street outreach, HIV / Hep C prevention, harm reduction worker) since 2010 at CACTUS-Montréal, a needle-exchange program downtown. He is currently doing an MA bridging public policy, social work, and critical social science. His research is about the displacement and dispersal of drug users and street-involved community in downtown Montréal following a period of widespread urban development and renewal in the late 1990s and early 2000s, and the cultural erasure at play in this process. The research looks at the impacts of shifts in public health and urban planning policy on street-involved community, on people’s health, on HIV risk and streetwork practice, and on forced economic migration within the city. His other research interests include policing, community-sector relations with the state, harm reduction, critical public health, and oral history.
