Watts founded the Gender Violence Research Centre at the London School of Hygiene and Tropical Medicine. This team collaborated in 2012 with Liz Kelly and colleagues at the Child and Woman Abuse Studies Unit, London Metropolitan University and Nicole Westmarland and her research team at Durham University's Crime, Violence and Abuse group to assess the impact of community domestic violence perpetrator programmes on women and children's safety, as well as investigating related questions such as which specific factors enable violent men to change their behaviour. The research was supported by Respect, the UK's umbrella organisation for domestic violence perpetrator programmes.
