Dr. Puzzo graduated in Experimental Psychology at the University of Padua (Italy) in 2004. Then obtained a MSc in research methods (2007) and a PhD (2010) in Psychology at the University of Essex (UK).

Prior to joining City University of London as a Lecturer Dr. Puzzo held a senior clinical scientist post at Broadmoor Hospital, West London Mental Health NHS Trust from 2015 to 2018.

His current research focuses on understanding the interplay between affective, neurocognitive and social factors contributing to the development of aggressive and antisocial behaviour in children and adolescents as well as in adults mentally disordered offenders.
