Stacy Hoskins Haynes joined the faculty at Mississippi State University in 2008 after receiving her Ph.D. from the Department of Sociology and Crime, Law, and Justice at Pennsylvania State University. Her research focuses on issues related to victimization, sentencing, juvenile justice, and criminal justice policy. Dr. Haynes's previous research has examined offenders' and victims' experiences in the criminal justice system, particularly with regard to restitution, and the effects of contextual factors on sentencing outcomes.

Current projects focus on the imposition and payment of economic sanctions among adult and juvenile offenders, individuals' attitudes towards juvenile justice, the effects of victim-related contextual factors on the criminal justice system, and the relationship between gender and fear of crime.
