Dr. David Day is a Professor in the Department of Psychology at Toronto Metropolitan University (TMU), Faculty of Arts. He holds a PhD from the University of Windsor and is a registered psychologist (C.Psych.). His primary research and teaching focus on developmental criminology and children's mental health.

His research interests center on understanding the developmental pathways of criminal behavior, particularly the early onset of antisocial conduct and its long-term trajectories. He investigates risk and protective factors in youth delinquency, community-level interventions, and the socioeconomic costs of crime. His work often involves longitudinal data analysis and community-based collaborations.

Dr. Day leads the Psychology of Criminalized and Risky Behaviours Lab (PoCRB Lab) at TMU, where he conducts empirical studies on criminal trajectories, forensic risk assessment, and youth behavior. His recent publications reflect a strong trend in integrating developmental psychology with criminological theory, particularly in examining peer influence, facial perception in criminal roles, and the validation of risk assessment tools in forensic populations.
