Investigation into the cause and prevention of gun injuries and fatalities began at the Johns Hopkins Bloomberg School of Public Health more than twenty years ago as part of an overall injury prevention research effort. Center Director Daniel Webster, ScD, MPH and Center Co-Director Jon Vernick, JD, MPH have gained national reputations as experts in gun policy and gun violence prevention research. The Center was formally established in 1995. Stephen Teret, JD, MPH is the Center's founding director and current faculty member focusing on firearm safety technology. Center faculty member Dr. Shannon Frattaroli, PhD, MPH is a leading researcher studying policies to prevent firearm-related domestic violence, and is among the first to promote the potential for Extreme Risk Protection Orders (also known as Gun Violence Restraining Orders) as a means for reducing suicides and homicides with firearms. Dr. Emma (Beth) McGinty focuses on how public policies affect mental health, substance abuse, and gun violence. Dr. Colleen Barry, PhD brings a wealth of expertise in public opinion research and leads studies of public opinion about policies to reduce gun violence. Dr. Cassandra Crifasi conducts research on how state policies affect the assault and homicide rates of law enforcement officers in the United States. Sheldon Greenberg’s research draws upon his many years of experience in law enforcement in their ongoing efforts to study the enforcement of gun policies.
