Expert panelists and presenters provide context about the problem and discuss evidence-based solutions that can have an impact on the local, state and federal levels.
Who We Are
The Center for Gun Violence Solutions combines the expertise of the country’s most respected gun violence researchers with the skills of the nation’s most experienced gun violence prevention advocates. We develop and apply scientific research to identify a range of innovative gun violence solutions and to advocate for systemic changes. This combination creates a unique opportunity to turn public health research into policy action that reduces all forms of gun violence and saves lives.

Public Health Approach to Gun Violence
A public health approach to prevent gun violence addresses both firearm access and the factors that contribute to and protect from gun violence. This multidisciplinary approach brings together a range of experts across sectors—including researchers, advocates, legislators, impacted communities, community-based organizations, and others—in a common effort to develop and implement equitable, evidence-based solutions.
Our Work in Practice
Our team synthesizes and applies the best available scientific evidence in conjunction with input from communities impacted by different forms of violence to develop policy and program recommendations to address gun violence. We inform relevant stakeholders of these recommendations by developing educational materials, including reports and issue briefs, conducting public forums, and submitting expert testimony.

How are they used? This simple but comprehensive tool can help everyone understand the different parts of a firearm and lead to more productive conversations about gun violence prevention.
