Jaclyn Schildkraut, PhD, is the executive director of the Regional Gun Violence Research Consortium. Prior to this appointment, she served as an associate professor of criminal justice at the State University of New York (SUNY) at Oswego. A national expert on school and mass shootings, Schildkraut’s work focuses on the effectiveness of policies aimed at prevention, mitigation, response, and recovery. Her most recent research, conducted as part of the largest study in the nation to date, examined the effects of school lockdown drills on participants and their skill mastery. In addition to being published in a book and multiple journal articles, the findings of this research are being used by school districts to help improve their emergency response plans. She also has conducted and published research examining the impacts of mass shootings on survivors, which led to her providing an expert report for Canada’s Mass Casualty Commission charged with investigating the April 2020 mass casualty event in Nova Scotia. Other recent projects have considered perceptions of armed teachers and policy responses to mass shootings.

Schildkraut is the co-author of Mass Shootings: Media, Myths and Realities (2016); Columbine, 20 Years Later and Beyond: Lessons from Tragedy (2019); and Lockdown Drills: Connecting Research and Best Practices for School Administrators, Teachers, and Parents (2022).

Before entering academia, AbiNader worked as a community victim services advocate in the fields of sexual violence, intimate partner violence, family violence, and commercial sexual exploitation/trafficking. She delivered primary prevention interventions from kindergarten through college, facilitated support groups in the community and in carceral settings, and provided advocacy services to incarcerated women.

She also has adjunct faculty appointments in the departments of Pediatrics and Psychology. She received her Ph.D. in 1992 from the University of Maryland. She has been conducting research with children of substance using parents for over 25 years. Many of these children experience significant levels of family and community violence since early childhood. The goal of her research has been to understand when and under what circumstances do developmental trajectories of children who are risk for maladjustment due to parental substance abuse and associated risks begin to diverge from normative trajectories? Are there developmental mechanisms that explain the association between these risk factors and children’s developmental and health outcomes? Are there experiences or individual differences in these children that promote resilience in the face of risk or increase the potential for maladjustment? If so, what are these, when do they occur, and are they amenable to intervention? All of this work has been supported by continuous funding mostly from the National Institutes of Health (NIH). She is currently Chair of the Psychosocial Development, Risk and Prevention Study Section in the NIH Center for Scientific Review, received the Clinical Translational Research Award from UB in 2017, and has been editorial board member on leading scientific journals in her field.

Professor Harvey is Professor of Politics, Affiliated Professor of Law, and Director of the Public Safety Lab at New York University. She has served as Chair of the Department of Politics and as Interim Dean of the Graduate School of Arts and Science. Her work with the Public Safety Lab uses the tools of data science and social science to promote cost-effective public safety, with an awareness of both resource and social costs. The Public Safety Lab works with communities and law enforcement agencies to design, implement, and test analytic solutions that meet jurisdictions’ needs. The Public Safety Lab is currently working with several law enforcement jurisdictions to design and build analytic solutions that address officer safety in responding to 911 calls, the potential for human error in the priority codes assigned to calls for service, and strategies to identify human trafficking victims from the online corpus of commercial sex ads and provider reviews. The Lab is also engaged in a randomized controlled trial of a platform that pushes an SMS-based survey to recent 911 callers, asking them to rate their experience of the police response. The Public Safety Lab is also developing and piloting a mobile application that will allow a community to partner with a policing agency to co-produce public safety. Through the app, criminal investigators will be able to communicate with civilians near the location and time of day of recently committed crimes, with the capacity to solicit and receive video, photographic, or textual information.

Dr. Miller is Professor of Health Sciences and Epidemiology at Northeastern University, Adjunct Professor of Epidemiology at the Harvard School of Public Health, and Co-Director of the Harvard Injury Control Research Center. Dr Miller is an expert in injury and violence prevention.

Dr. Michael Siegel is a Professor in the Department of Community Health Sciences at the Boston University School of Public Health. During his 21 years at the School, his main areas of research interest have been alcohol, tobacco, and firearms. Tying these issues together is the presence of powerful corporations that use sophisticated marketing, public relations, and lobbying activities to negatively impact the public’s health. In the tobacco area, Dr. Siegel has examined the impact of cigarette advertising on youth smoking behavior, the health effects of secondhand smoke, and the evaluation of policies to reduce youth smoking and encourage smoking cessation. In the alcohol field, he has examined the relationship between alcohol advertising and youth alcohol consumption at the brand level. Recently, he has initiated a program of research into firearms violence. In September 2013, he published an article in the American Journal of Public Health which examined the relationship between state-level gun ownership and firearm homicide rates throughout the United States during a 30-year period. This research found a strong correlation between increasing prevalence of gun ownership and higher firearm homicide rates. A subsequent paper, published in AJPH the following year, reported that this relationship between gun ownership and firearm homicide was only present for non-stranger homicide rates, not for stranger homicide rates. His current work focuses on examining the impact of state firearm laws on rates of firearm-related homicide and suicide, studying the role of gun culture in the epidemic of firearms violence, and exploring the effects of state-level firearm laws on homicide rates among African-American and Hispanic populations.
