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 has been the Chair of Gloucestershire Constabulary's Ethics Committee since 2017. Since 2018 she has been a member of the UK National Crime Agency's Independent Reference Group. She is also a member of the Independent Digital Ethics Policing Panel. In 2020 she was appointed as a member of the Metropolitan Police's first Research Ethics Committee (MetREC). 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.
