Manchester Metropolitan University (MMU) provide analytical, research and evaluation support to the VRU. This ensures that decision-making utilises a robust evidence base. We undertake analytical surveillance work to understand the extent and nature of the violence problem. We research and evidence the causes of violence, identifying the risk and protective factors. We support the VRU and partners to develop interventions to address violence and the causes of violence. We work with partners to ensure that appropriate evaluations are undertaken, to understand what works and for whom. We disseminate findings through policy and academic literatures to enhance the evidence base.
