Doctor Samantha Colledge-Frisby

Research Fellow


Samantha completed her PhD at the National Drug and Alcohol Research Centre, UNSW in Sydney. Her thesis was concerned with physical and mental health harms that disproportionately implicate people who inject drugs and strategies that may prevent these harms from occurring.

She has collaborated with global agencies, such as the United Nations Office on Drugs and Crime, the World Health Organization, and the Global Burden of Disease project, in improving global estimates of injecting drug use and associated harm. She is currently posted at the National Drug Research Institute (NDRI) Melbourne where she will be working to expand on our understanding of injecting-related infections and evaluating harm reduction services.
