Dr. Beidi Dong is an Associate Professor of Criminology, Law and Society at George Mason University. He earned his PhD from the Department of Sociology and Criminology & Law at the University of Florida and completed postdoctoral fellowship in the Department of Biostatistics, Epidemiology and Informatics at the University of Pennsylvania. His research interests revolve around identifying risk and protective factors for community violence in the United States and developing evidence-based strategies to prevent and alleviate the negative impacts of violence on affected individuals and communities equitably. His research also addresses health disparities and inequities associated with crime/violence and punishment.

His research largely draws from two theoretical perspectives. The life-course perspective stresses the significance of life-span and intergenerational development as a unifying idea. It is essential to understand the onset, timing, duration, intensity, persistence, and desistance of criminal offending and explore the effects of life circumstances and events on the course (both stability and change) of offending (e.g., see his research on life-course trajectories of gang members and gun carriers). The socio-contextual perspective, on the other hand, emphasizes the role of neighborhood conditions and proximate micro-geographic locations in shaping individuals’ routine activities and the likelihood of crime and violence (e.g., see his research on the geographic overlap of violent crime hot spots and ill health, situational triggers of gunshot assault, and disparities in urban gun violence). 

From a methodological standpoint, he employs various quantitative and computational social science methods to enhance public safety and health.
