David Day, a professor at Ryerson University in Canada, has a similar interest in psychology and criminology, plus experience working as a psychologist at a medium security prison. The two teamed up to write the book “Criminal Trajectories: A Developmental Perspective,” published in 2019 by NYU Press. It was nominated for the Social Policy Publication Award from the Society for Research on Adolescence.
