Dr Hannah Gaffney

Dr Hannah Gaffney is a member of the Violence Research Centre at the Institute of Criminology, Cambridge. She was awarded her PhD in Criminology in 2020 from the University of Cambridge. Dr Gaffney’s doctoral research concerned ‘what works’ in school- and cyber-bullying intervention and prevention programmes. Her work demonstrates that school programmes can be implemented to reduce bullying amongst youth, and that the effectiveness varies according to specific features of intervention programs and evaluation methodologies.

Dr Gaffney was appointed the Betty Behrens Research Fellow at Clare Hall, where her work will focus on examining ways in which violence (particularly sexual violence, intimate partner violence and hate-related violence) can be prevented using sexual and relationship education programmes in schools.
