Gun violence is happening almost daily in small towns and larger, urban areas across the U.S. The University of Pennsylvania has a variety of experts to discuss the many perspectives related to gun violence—from the medical treatment of gunshot victims to the policies surrounding domestic violence and firearms.
As an implementation scientist and clinical psychologist, Dr. Beidas uses evidence-based firearm safety promotion approaches in pediatric primary care settings to reduce unintentional and intentional firearm injuries in youth. She partners with a diverse set of stakeholders, including gun owner constituents, to understand how best to realize this goal.
Dr. Holena specializes in the treatment of traumatic injury, emergency general surgery conditions, and surgical critical care. He studies the quality of care after injury, with a specific interest in the methodology used for risk-adjusting trauma morbidity, mortality, and failure to rescue. He is also part of the Penn Injury Science Center, which performs research, provides training, and translates scientific discoveries into practice and policy.
Dr. Jacoby combines nursing and public-health perspectives in her approach to injury science and urban health research. As a nurse in a Philadelphia ICU, Dr. Jacoby witnessed the profound trauma and violence that impacted the lives of hospitalized patients and their families. This inspired her to study the experience of injured people and the social and structural determinants of racial and ethnic disparities in trauma outcomes. At the Penn Injury Science Center, Dr.
Dr. MacDonald works on a variety of topics in criminology, including the study of crime and violence; race and ethnic disparities in criminal justice; and the effect of public policy responses on crime. Recent work has looked at the effect of greening vacant lots, finding that neighborhoods where such lots were cleaned up experienced a 29 percent reduction in gun violence and 7 percent reduction in fatal and nonfatal shootings. He is also part of the Penn Injury Science Center, which performs research, provides training, and translates scientific discoveries into practice and policy.
For more than two decades, Dr. Richmond has studied the physical and psychological toll of injuries and trauma. Using nursing science, she works to determine ways to prevent firearm violence and injury and improve outcomes, particularly for vulnerable populations. She co-founded the Firearm & Injury Center at Penn, now called the Penn Injury Science Center, which performs research, provides training, and translates scientific discoveries into practice and policy.
Dr. Sorenson has a unique interdisciplinary background in epidemiology, sociology, and psychology. She moved to Penn in 2006 after more than 20 years at the UCLA School of Public Health. Since 1986, she has taught a graduate course in family and sexual violence—the first violence-prevention course in a school of public health in the nation. She currently teaches three courses that she developed: “Foundations of Public Health,” “Guns & Health,” and “Non-stranger Violence.”
One of the nation’s leading authorities on effective parenting and African-American psychology, Dr. Stevenson can discuss how parents can talk to children about violence and tragedies. He can discuss behavioral indicators that a child might be experiencing post-traumatic stress disorder, youth resiliency and the psychological adjustment of children, adolescents and families, particularly after a horrific event.
