Gun Violence Epidemiology

Violence and Firearm Injury Epidemiological Studies Using National and State Databases

In collaboration with Drs. Elinore Kaufman (University of Pennsylvania), Eduard Coupet (Yale), and Douglas Wiebe (University of Pennsylvania), we have investigated epidemiological trends in gun violence.

To accomplish these objectives, we have used large national and state datasets to describe the epidemiology of nonfatal and fatal injuries from violence and firearms in terms of health outcomes and costs.
