Marc Le Blanc is Emeritus Professor at the University of Montreal's School of Criminology and School of Psychoeducation. He served as Director of Research for Boscoville, a research and development center for adolescents with problem behavior. He has been involved in fundamental and applied research concerning juvenile delinquency for the last 50 years and in promoting a developmental approach to the study of crime. He has also worked on the ecology of delinquency in Montreal, changes in the phenomenon of delinquency over the past 50 years, the gang phenomenon, substance use and female delinquency. His work in applied criminology concerns the evaluation of treatments for juvenile delinquents and the functioning on juvenile justice. He developed and validated an instrument for the evaluation of juvenile delinquents based on his integrative theory. He has also implemented experimental differential treatments (cognitive behavioral and developmental) in secure and open units for serious delinquents. Professor Le Blanc has also been engaged in a consultative capacity to various governmental and nongovernmental organizations in Canada, America and Europe. Professor Le Blanc was elected to the Social Sciences Academy of the Royal Society of Canada and is a Beccaria, Killam, deToqueville-Beaumont and Sellin-Glueck Fellow. He received a lifetime achievement award from the Government of Québec and the American society of criminology and a Doctorate Honorius causa from University of Liège. He has contributed to ongoing debates about paradigmatic topics such as developmental criminology, advanced criminological theory by constructing multilayered developmental theories of self- and social control, and supplemented empirical knowledge through cross-sectional and longitudinal research.
