Dr Sarah Larney is an Assistant Professor at the University of Montreal and adjunct Senior Lecturer at the National Drug and Alcohol Research Centre (NDARC), University of New South Wales. Her research focuses on injecting drug use and related problems - including problems that arise from injecting (e.g. HIV and hepatitis infections; bacterial infections; injecting injuries), and problems arising from the types of drugs injected (opioid use disorder and its treatment; methamphetamine-related health problems). She works to generate high-quality epidemiological data on injecting drug use and related problems in Australia and internationally, and to use these data to a) improve the safety, efficiency and targeting of current responses to injecting drug use, and b) to develop new responses to neglected harms (e.g. skin infections) of injecting drug use.
