The Criminological Research Institute of Lower Saxony (KFN) is an independent research institute mainly dedicated to understanding the preconditions and consequences of crime. Our criminological research is fundamental, practice-oriented, and interdisciplinary. We currently employ around 20 scientists from the fields of criminology, law, sociology, political science, and psychology, as well as a large number of student assistants and interns. The KFN is divided into three research units: Aetiology of Deviance, Victimology, and Institutions of Social Control, which are supported by a Methods Department.
