Rate My Professor Christina Marel

Her research examines mental and substance use disorders in complex populations, focusing on heroin dependence, co-occurring post-traumatic stress disorder, depression, trauma exposure, long-term remission, treatment use, and mortality. She has coordinated the 11-year and 18-20-year follow-ups of the Australian Treatment Outcome Study, a cohort of 615 people entering heroin treatment in 2001-2002. Marel led development of two editions of National Clinical Guidelines on managing co-occurring alcohol, other drug, and mental health conditions, funded by the Australian Government Department of Health and Aged Care, with accompanying training. She holds NHMRC Fellowships, contributed to NHMRC Project Grant APP1147212, and received the Matilda Centre Community Impact and Engagement Award as Comorbidity Project team lead. Key publications include 'Patterns and Correlates of Sustained Heroin Abstinence' (2015), 'Modelling Long-Term Joint Trajectories of Heroin Use and Mental Disorders' (2020), 'Correlates and predictors of PTSD among people with heroin dependence' (2025), and 'A systematic review and meta-analysis of the prevalence of alcohol and other drug use among people accessing mental health treatment in Australia' (2025). With 1958 Google Scholar citations, her work influences clinical practice and policy. She supervises PhD students.
