In 2013, the co-directors of the Violence Prevention Initiative (VPI) sought the input and expertise of a multi-disciplinary group of clinicians and researchers from across Children’s Hospital of Philadelphia (CHOP) to help set direction and priorities for the new initiative. Each VPI Fellow offers a unique perspective to the causes and impact of violence on our children and youth, as well as solutions.
The result is a powerful network of violence experts that helps the VPI to be strategic and practical in its efforts, as well as nimble in our ability to respond to violence and crisis in our communities. Continue reading to learn more about each Fellow and their specific area of expertise.
