Joshua Horwitz

JOSHUA HORWITZ, JD, is the inaugural Dana Feitler Professor of the Practice in Gun Violence Prevention and Advocacy in the Department of Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health. He also serves as co-director of the Johns Hopkins Center for Gun Violence Solutions.

Horwitz is a leading gun violence prevention advocate and expert. He has spent over three decades working on gun violence prevention issues by utilizing public health research and health equity analysis to build advocacy campaigns that meet critical opportunities in the policy development process.

As part of the Educational Fund to Stop Gun Violence, Horwitz helped develop and advance Extreme Risk Protection Order laws that allow the court to temporarily remove firearms when there are clear warning signs of imminent violence. To date, ERPO laws have been adopted in 19 states and Washington, D.C. Research shows they are effective in reducing both suicides and mass shootings.

Horwitz led the development of a bill in California that required all semi-automatic firearms made or sold in California to be micro-stamped, a technology that makes it easier for law enforcement to match cartridge casings to a firearm and its purchaser. California enacted the law in 2007, and the laws have also recently been passed in New Jersey and New York.

Following the Sandy Hook Elementary School shooting in 2012, Horwitz co-founded the Consortium for Risk-Based Firearm Policy, a group of experts including researchers and practitioners, to advance evidence-based gun violence prevention policies. He has served as the Consortium’s director since its inception. The Consortium continues to provide recommendations that inform legislation, executive action, and policy implementation.
