His additional research interests include the effects of perinatal disorders as an influence in future criminality, the etiology of white-collar crime, and gang intervention. nbsp; Dr. Tibbetts has published nine books and more than 50 scholarly papers examining various issues in criminology. He received the 2011 Outstanding Professor Award at CSU, San Bernardino.
