I am a criminologist and senior research fellow based at the Research School of Psychology at the Australian National University (ANU). My research covers violent extremism, terrorism, radicalisation, prison radicalisation, community-led youth interventions, correctional reform, and gangs. I have published extensively and have a new book recently released by Routledge titled, Inmate Radicalisation and Recruitment in Prisons. Before moving into academia in 2010, I worked for over 15 years in several areas of national security, including police, military and intelligence. I am currently advising Philippines corrections on the management of high-risk inmates, violent extremist offenders, and prison reform. I also regularly train and brief other international governments in these areas. In 2015, I was the founding director of the Australian Intervention Support Hub (AISH) at the ANU, which was an initiative aimed at supporting government and community countering violent extremism (CVE) efforts through the provision of multidisciplinary research. Following on from AISH, I now partner with several Muslim community organisations in Melbourne and Sydney, Australia, including some of the most conservative and hard-to-reach groups, to co-design and implement culturally and religiously sensitive, community-driven, and evidence-based responses to anti-social youth behaviours. To achieve better ecological validity, I have developed long-term trusted friendships by participating in youth camps, sporting activities, religious lectures, religious events/festivals, family occasions, and council (or Shurah) meetings. For the past eight years, I have also worked as a private consultant, particularly around prison and sentencing reform and crime prevention. I have recently completed two reviews of Aboriginal and Torres Strait Islander offender rehabilitation and parole programs in Australia, a review on prison radicalisation in Australia’s correctional system, and a report on the efficacy of CVE programs in schools for government and non-government agencies. In 2002, I was the 2002 Chief of the ADF Force Fellow and, based on this fellowship, completed my PhD at the University of New South Wales in 2010. I also hold a Masters (by research) in Criminology, and a degree in Criminal Justice Administration from RMIT University.
