Dr. Eileen M. Ahlin is an Assistant Professor of Criminal Justice in the School of Public Affairs at Penn State Harrisburg. She received her M.A. in Sociology (with a focus in Crime, Delinquency, and Corrections) from George Mason University and her Ph.D. in Criminology and Criminal Justice from the University of Maryland, College Park, in 2010. Her research focuses primarily on how formal and informal social controls across the ecological framework buffer against violent offending and exposure to violence in the community and correctional settings. Currently, Dr. Ahlin is using data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to examine the relationship between violence and communities, and how family management, peers, and youth characteristics serve as risk or protective factors. In addition, she is studying risk factors associated with violence among youth in custody in detention centers, jails, and prisons. Her research appears in the journals such as Youth Violence and Juvenile Justice, Journal of Interpersonal Violence, Journal of Youth and Adolescence, Aggression and Violent Behavior, Journal of Criminal Justice, and American Journal of Public Health. She is a co-recipient of the 2016 W.E.B. Du Bois Fellowship from the National Institute of Justice, for research examining the role of immigrant generation status and race/ethnicity on the effects of inner-city mobility on youth violence and exposure to violence.
