Ms Elizabeth Treston
Forensic Psychologist currently working for the Australian Federal Police in the ACT. I have previously worked as an accredited Defence Force Recruitment Psychologist and with the Forensic Liaison Service with ACT Health. Completed my Masters of Forensic Psychology at Bond University in 2018 and am in the process of obtaining my PhD. My Masters thesis involved the analysis of crime scene characteristics between mentally-disordered and non mentally disordered offenders which helped to gain perspective on the mindsets of offenders during homicides and how these were reflected in the crime scene. I’ve completed numerous placements in high-risk, high secure environments as well as communal organisations, such as Youth Justice. I’m genuinely passionate about how Forensic Psychology can contribute towards the dynamics of psychology as a whole and why it is so important as a discipline itself.
