The academic work of Dr Ttofi revolves around two main areas, namely: (a) psychological criminology, with a focus on early intervention research and developmental criminology; and (b) experimental criminology, with a focus on systematic reviews, meta-analyses and programme evaluation, especially in the area of developmental prevention.
Research interests include early crime prevention and health promotion initiatives; health/criminal consequences of school aggression and peer victimization
