Dr. Small’s work has applied social science methods to study public health problems among illicit drug users, with a focus on HIV prevention and interventions designed to reduce drug-related harm. His current research program applies ethno-spatial epidemiological methods to examine the impact of social, structural and physical environments on HIV risk behaviour and HIV treatment-related outcomes among illicit drug users. This work employs an interdisciplinary approach integrating ethnographic observational fieldwork, in-depth interviews, and geo-spatial mapping techniques in connection with three prospective epidemiological cohort studies of illicit drug users based in Vancouver
