Full Profile

Michelle's doctoral research is the first to examine how the police deal with this high volume crime and prioritise those offenders who are most likely to be committing hands on child sexual abuse. In addition to the research’s intellectual appeal, it is policy relevant in helping to generate evidenced based decision tools for police intelligence assessment. Her doctoral research assisted with the creation of KIRAT (Kent Internet Risk Assessment Tool), a risk management tool for individuals accessing indecent images of children. KIRAT was recently reported within CEOP’s thematic assessment (2012) as “the most rigorously tested assessment tool currently available” (p.11). This tool has been accredited by ACPO to be used by all Police Forces within the UK, and recently received funding to be extended to Europe, with International development due to commence in 2013.

Dr. McManus worked as an analyst and researcher for various Constabularies since 2009. This work involved development and rollout of risk management strategies in assisting with high frequency crimes, training child exploitation teams, with presentations and training to law enforcement and academic organisations internationally. She lectures and has published in various areas of policing and has been a Justice of the Peace since 2007.
