Marie started working at Redeemer in July of 2014. She is a developmental psychologist who is fascinated by the role that spiritual and religious beliefs play in the social, emotional, and physical well-being of adolescents and young adults. In her doctoral work in Brock University’s Adolescent Development Lab, she focused examining on the difference between “religiosity” and “spirituality”, particularly in terms of how they are differentially related to emotional well-being and engagement in risky activities (e.g., substance use). Her doctoral finding that religiosity (but not spirituality) tended to predict lower engagement in alcohol use, led to a postdoctoral fellowship in the Social Neuroscience Lab at the University of Toronto, where she studied cognitive and neural mechanisms that may help explain why religious adolescents drink less than their non-religious peers. She has published her findings in journals such as Developmental Psychology, Social Cognitive and Affective Neuroscience, Religion Brain and Behavior, and Journal of Youth and Adolescence. With collaborators at Brock University and University of Guelph, she has also dabbled in research on general risk-taking and mental health in adolescence. For example, she has published work on identity development; the functions of non-suicidal self-injury; the relation between violent video games and aggression; and the association between depression and risk-taking behaviours.
