Kat is a criminologist and applied philosopher. Her work examines the ethical and human rights aspects of developments in criminal justice and policing, especially around the use of surveillance technologies, data-driven policing, and human trafficking. She has worked on a number of EU-funded research projects examining the ethical implications of police use of social media and surveillance tech, in contexts such as counter-terrorism and child sexual abuse and exploitation online. Her most recent publications examine the spread of self-styled paedophile hunters (2019 Criminology and Criminal Justice) and anti-slavery policy at the UK border (2018, European Journal of Criminology). Kat has provided consultation to the UK Borders Agency, Frontex, on their Code of Ethics. She is the Chair of Gloucestershire Police Ethics Committee. She sits on the UK National Crime Agency’s Independent Reference Group. And she is a member of the Independent Digital Ethics Policing Panel.
