Biography

Dr. Day entered the applied social psychology graduate program (community psychology stream) at the University of Windsor in 1982, with a particular interest in community mental health and psychosocial rehabilitation.  His doctoral work focused on psycho-epistemology as a predictor of attitude change. 

In 1989, he became Director of Research and Evaluation at Earlscourt Child and Family Centre (now the Child Development Institute) in Toronto.  Earlscourt specialized in the treatment of children, ages 6 to 11 years, with conduct problem behaviours.  His research focused on the factors that contribute to an early onset of antisocial behaviour, including those behaviours that would be criminally chargeable if the child was over age 12 years.  This led to an interest in developmental criminology and work as a staff psychologist at a medium security prison for adult male offenders, prior to becoming a faculty member at Toronto Metropolitan University (TMU) in 1998.

At TMU, he has continued to pursue his dual interests in developmental criminology and children’s mental health. He is the Director of the Psychology of Criminalized and Risky Behaviours Lab (PoCRB Lab). One of his major programs of research was a longitudinal investigation of developmental risk factors and criminal trajectories in a sample of 764 male offenders. This project also involved an investigation of the longitudinal costs of crime. On this topic, he published his book Criminal trajectories: A development perspective, with Dr. Margit Wiesner in 2019. A second study examined the impact of a school-based program for students in grades 9 and 10 on stress and coping. He particularly enjoys research at the community-level and has been fortunate to be able to continue this work with various agencies and organizations.

Dr. Day’s teaching activities at TMU parallel his research interests and have included Special Topics in Social Psychology – Forensic Psychology, Advanced Social Psychology Seminar, Psychology of Criminal Behaviour, Social Psychology, and Developmental Psychopathology.
