Kat's work is at the intersection of moral philosophy and criminology. Her work examines the implications - especially the ethical implications- of developments in technologies and data for security, criminal justice and policing. Areas of expertise include surveillance technologies, data-driven policing, and human trafficking. She is currently contributing to the policing and surveillance stream of the ESRC-funded Human Rights, Big Data, and Technology project. Kat is the Chair of Gloucestershire Constabulary's 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. Kat is also a volunteer for Age UK, where she gives advice and support to people in planning end-of-life care and planning for death.
