Dr Hannah Siân Hammond

Dr Hannah Hammond (née Baumer) is a Chartered Psychologist and Lecturer in Health Psychology. She completed her PhD at Royal Holloway in 2018 and has since led impactful research on sport, motivation, and desistance from crime—both as a consultant and with the University of Birmingham.

Her work explores how sport can promote rehabilitation in prisons and support young people in the community to move away from crime. Hannah has published on topics including prison sport motivation, healthy prison cultures, and sporting masculinities.

She recently led the evaluation of Levelling the Playing Field, a national pilot tackling racial disproportionality in youth sport and justice—earning a feature on BBC Wales and a speaking invitation to Parliament. Hannah is a passionate advocate for sport as a tool to address health and social inequalities.

She is an Associate Fellow of the Higher Education Academy and serves on the Violence Reduction Unit/PCC Sport, Youth Crime and Serious Violence Prevention Board.
