This week we spoke with Volkan Topalli who is a professor of criminology at Georgia State University and co-editor of the journal Criminology. We talked to Volkan about his active offender approach to research going back to where it really gained popularity: the University of St. Louis-Missouri.    Volkan has published in journals such as Criminology, Justice Quarterly, and Criminal Justice and Behavior.
