While living on Jerome Avenue and attending City College of New York (CCNY) in the 1960s, he was swept up in the social and political currents of the time. He became intrigued with the influence contemporary culture had on individual behavior: Did people shape society or did society shape people? He applied his interest in social forces and human behavior to the study of crime and justice. After graduating from CCNY, he attended the newly opened program in criminal justice at the State University of New York at Albany, earning both his M.A. and Ph.D. degrees there. After completing his graduate work, Dr. Siegel began his teaching career at Northeastern University, where he was a faculty member for nine years. After leaving Northeastern, he held teaching positions at the University of Nebraska-Omaha and Saint Anselm College in New Hampshire. He then taught in the School of Criminology and Justice Studies at the University of Massachusetts-Lowell for more than 26 years. Now a Professor Emeritus, he continues to teach online courses. Dr. Siegel has written extensively in the area of crime and justice, including books on juvenile law, delinquency, criminology, criminal justice, and criminal procedure. He is a court certified expert on police conduct and has testified in numerous legal cases.
