Dr Monica Barratt is a social scientist at the Drug Policy Modelling Program, part of Australia's National Drug and Alcohol Research Centre at the University of New South Wales. She is also an Adjunct Fellow at the National Drug Research Institute, Curtin University, and a Visiting Fellow at the Burnet Institute. Monica has been working in the drugs field for more than a decade, and was recently awarded the highly competitive National Health and Medical Research Council Early Career Researcher fellowship to continue her work on the social and public health implications of internet technologies for people who use illicit and emerging psychoactive drugs. Research topics emerging from this interest include online drug markets or cryptomarkets and policy responses to novel psychoactive substance evolution. She specialises in engaging hard-to-reach networks and groups in digital spaces in conversations about research and policy. Through this engagement, Monica's work acts as a conduit between these groups and policy makers, and contributes to policy change. Monica also serves as an associate editor at the International Journal of Drug Policy, and as the Director of Research at the international drug harm reduction community Bluelight.org.
