Manuel Eisner is Wolfson Professor of Criminology at the University of Cambridge, and Deputy Director of the Cambridge Institute of Criminology. He researches the history of interpersonal violence,[1] and has conducted a study on levels of homicide throughout Europe over a period of 800 years.[2][3] His research has highlighted the ways in which cultural models of conduct of life, embedded in social institutions, have shaped patterns of daily behaviour among adolescent and young adult men, which in turn have influenced the likelihood of frictions leading to aggressive behaviour.[4] He is also recognised for his studies on the developmental causes of crime and delinquency[5] and advocates the effectiveness of early prevention during childhood. Recent projects include the London Medieval Murder Map[6] and the Evidence for Better Lives,[7] a global birth-cohort study in eight cities across the world.[8]
