Julia Rozanova is a Lecturer in Global Mental Health at King's College London, where she also co-directs Global Mental Health MSc programme. She received her PhD in Sociology from the University of Alberta, and subsequently trained in Social Gerontology at Brown University. She then completed two postdoctoral fellowships, in Urban Ethnography with Prof Elijah Anderson at Yale Sociology Department, and in Implementation Science at Yale School of Medicine.

Dr Rozanova's research has been funded by the Alberta Heritage Foundation, Canadian Institutes of Health Research, Social Sciences and Humanities Research Council of Canada, National Institute of Drug Abuse, National Institute on Mental Health, National Institute on Aging, and most recently, National Institute of Health Research (NIHR).

Dr Rozanova has an active research interest in addictions and opioid use disorder, and she has led studies with criminal justice populations in Kyrgyzstan focusing on improving linkage to treatment. In partnership with Professor Sir John Strang, she co-leads a Prison Release Engagement Trial, that investigates the ability for an app-based contingency management tool to improve linkage to treatment within 21 days post-release among prison-leavers with heroin use history in England.

With colleagues from the United States and from Ukraine, Dr Rozanova conducts research at the intersection of HIV, addiction, and aging in Ukraine. This work examining how older adults with HIV cope during the humanitarian crisis has continued throughout the full-scale Russian invasion.
