Dr Hannah Gaffney
Dr Gaffney was appointed Betty Behrens Research Fellow at Clare Hall in October 2020.
Since then, her work has primarily focused on understanding what works to reduce the involvement of children and young people in crime and violence. This has included working the Youth Endowment Fund in creating a Toolkit to summarise the evidence on the effectiveness of different intervention programmes for children and young people.
Dr Gaffney’s research has also recently found that sports interventions are an effective way to prevent children and young people from being involved in crime and violence. Her research interests are broad and generally related to prevention and intervention in youth crime and violence, but she also has a keen interest in meta-analytical models and methods.
Hannah is an affiliated member of the Violence Research Centre, at the Institute of Criminology, Cambridge where she completed her PhD. Her doctoral research evaluated the effectiveness of anti-bullying programmes in schools. Hannah is also the current Associate Editor of Aggression and Violent Behaviour. Prior to coming to Cambridge, Hannah received her MSc in Forensic Psychology from the University of Kent. She has a BA in Psychology from Maynooth University, Ireland. Originally from Dublin, Hannah now lives in Cambridgeshire with her partner and new puppy Roger. She is an avid knitter and coffee drinker!
