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. Her work is funded via the National Health and Medical Research Council (Early Career Fellowship and Project Grant schemes).

Over the last 15 years, Monica's research has examined the social and public health implications of digital 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, including live mapping of drug misrepresentations through community-based drug checking or testing services. She specialises in engaging hard-to-reach networks and groups in digital spaces in conversations about research and policy, to inform policy change.

Monica is also an Adjunct Fellow at the National Drug Research Institute, Curtin University, and a Visiting Fellow at the Burnet Institute. She serves as Associate/Deputy Editor for the journals International Journal of Drug Policy and Drug and Alcohol Review, Australian Research Lead on Global Drug Survey, and Director of Research at the international drug harm-reduction community Bluelight.org.
