Kat's research is at the intersection of criminology and ethics. Her work examines developments in technologies and data for policing, criminal justice and security. Areas of expertise include domestic abuse, surveillance, criminal records, and human trafficking. Ongoing funded projects include a Home-Office funded study on domestic abuse perpetration, a 3-year ESRC-funded SeNSS PhD studentship, and a London Mayor's Office for Policing and Crime-funded study of responses to domestic abuse amongst children and young people. Kat is Chair of the British Society of Criminology's Policing Network. She is also a member of various policing and ethics committees. In 2021 she led the academic subgroup of a Home Office Task and Finish working group on revised guidance for the Domestic Abuse Disclosure Scheme. Since 2018 she has been the Chair of Gloucestershire Constabulary's Ethics Committee and a member of the UK National Crime Agency's Independent Advisory Group on Ethics. In 2020 she was appointed as a member of the Metropolitan Police's first Research Ethics Committee (MetREC), and a member of HMRC's first Professional Standards Committee. In 2021-22 she is serving on the College of Police Code of Ethics Review Committee. She also has various advisory and consultancy roles as an independent ethics reviewer of technology research project proposals and projects, mainly for the European Commission. Kat is a long-time volunteer for Age UK, where she run a reminiscence group and gives advice and support to people in planning for the end of life.
