During his studies Professor Sarnecki also worked part-time at several youth recreation centres. This experience influenced the direction his research was to take and although he gained his PhD in sociology he became an expert on Swedish juvenile delinquency and moved into the field of criminology. After a spell working at the Swedish National Council for Crime Prevention, where he was recruited for his work on juvenile delinquency, he took up the chair of criminology at Stockholm University in 1993.

Since then Professor Sarnecki has been involved in the emergence of criminology as a leading academic discipline.

"Even every small university has courses in criminology," says Sarnecki. "There's been an enormous explosion of interest in this field of research."
Sarnecki, whose position is officially entitled Chair of General Criminology, retains his long-standing interest in the question of crime amongst young people in Sweden. He is currently leading a longitudinal research project entitled: “The Stockholm Life Course Project: Life-Courses and Crime In the Swedish Welfare State Through Half a Century”. This research follows up on two previous studies of men who participated in the Clientele Study of 1956, and Jonssons and Kälvestens 322
Another area of Sarnecki research is the use of network theory and methodology for the study of crime. He is currently working on two research projects with this focus. The project team includes in addition to criminologists also sociologists and physicists.
Sarnecki has also written on social reactions to crime and how different institutions within and outside the judicial system operates. Currently he is working on issues related to the saturation of the police.

"I think it's important there is a prize for work in criminology," says Sarnecki. "There is considerable interest in crime prevention in society. As researchers we have an important part to play in the policy making process. We need to have improved knowledge on the causes of crime, effective public polices for dealing with offenders and greater knowledge of alternative crime prevention strategies inside and outside the judicial system."
