The Violence Prevention Project (VPP) is a nonpartisan, nonprofit research center that focuses on reducing violence through rigorous and accessible research. Founded by Dr. Gillian Peterson, a psychologist, and Dr. James Densely, a sociologist, VPP takes an interdisciplinary approach to understanding violence. Their team and advisory board bring diverse backgrounds and real-world experience, which shapes their research and makes it applicable and relevant. VPP maintains databases, such as the US Mass Shootings and Shooters.
