Dr Lorenzetti is Senior Lecturer, Lead of the Neuroscience of Addiction & Mental Health Program and Deputy Director of the Healthy Brain and Mind Research Centre, at the School of Behavioural and Health Sciences, Faculty of Health, Australian Catholic University.

Her research program aims to map vulnerability to and recovery of brain and mental health harms in chronic addictions and psychopathology. An additional goal is to establish consensus-based gold standards to measure substance use and misuse in research, treatment and public health settings.

Dr Lorenzetti' long-term vision is to carry out world-leading research on the pathophysiology of addiction and to alleviate its devastating harms on ~55M people globally, by combining advanced multimodal neuroimaging tools, global multi-site cohorts and new interventions.

Her Program welcomes national and international student exchange.

Examples of research questions examined by the Neuroscience of Addiction and Mental Health Program include:

- Who is most vulnerable to brain and mental health harms, among substance users?

- Which neurobiological mechanisms differentiate young adolescent substance users who are vulnerable to brain and mental health harms, from those who are resilient to these harms?

- How to mitigate brain and mental health harms in chronic addictions? We explore the role of mindfulness-based strategies that target craving, and CBD-based interventions.

- How does cannabis potency affect brain integrity, and what is the role neuroprotective and neurotoxic cannabinoids in driving and mitigating brain harms in cannabis users?

- How does recreational and dependent substance use differ at a neurobiological level?

- How do men and women differ in the neurobiology of substance use?
