Associate Professor Carleen Thompson

Carleen Thompson is an Associate Professor in the School of Criminology and Criminal Justice and a Member of the Griffith Criminology Institute (GCI) at Griffith University. Carleen is Co-Lead of the Queensland Cross-Sector Research Collaboration (QCRC) and a Project Investigator in the 'Transforming Corrections to Transform Lives' Centre. Carleen is a member of the Social Analytics Lab (SAL) Committee, and is the data lead for the QCRC and TCTL SAL holdings. Carleen is Co-Lead of one of GCI's three core Research Programs 'Safer Societies'.  Carleen’s research aims to improve understanding of the causes and progression of offending to drive evidence-based intervention planning that reduces re-offending. Carleen has established strong partnerships across government departments, with 20 years’ experience using her research to help policy-makers and practitioners more effectively target interventions on the basis of offenders’ risks and needs. Her research has led to state-wide changes in risk assessment practices across adult corrections, youth justice and child protection, as well as reforms to frontline policing responses to low-risk offenders. Risk screening tools she developed have been used in Corrective Services throughout Queensland, South Australia and Western Australia for more than a decade.

Dr James Ogilvie

Dr Ogilvie is a psychologist and lecturer in the School of Criminology and Criminal Justice, Griffith University. His current research is focused on examining the intersection of mental illness and offending using population-level linked administrative datasets from criminal justice and health agencies. His broader research interests are on the causes of youth offending and the development, implementation and evaluation of interventions to reduce reoffending. Dr Ogilvie previously worked for 10 years as a practitioner (psychologist) with the Griffith Youth Forensic Service (GYFS), which operates as a joint partnership between Griffith University and the Queensland Government Department of Youth Justice to deliver assessment and treatment services for young people who have engaged in sexually harmful behaviour. He specialised in the delivery of assessment and treatment services in remote Indigenous communities. In this role, Dr Ogilvie gained extensive experience in the assessment and treatment of sexual violence committed by youth, including collaboration with families and community services to reduce the risk of reoffending and improve the outcomes for youth. Given his clinical background, Dr Ogilvie places a strong emphasis on the development of evidence-based practice.
