Research Interests

I am interested in understanding the psychological correlates and mechanisms of psychological health and behaviour across various populations including youth, adults, and individuals diagnosed with osteoporosis. I examine all aspects of the psychological health continuum including ill-being (e.g., symptoms of depression), hedonic well-being (e.g., positive affect), and eudaimonic well-being (e.g., vitality). The behaviours I am interested in understanding include physical activity and recreational screen time (e.g., watching TV, playing video games). In an effort to better understand how to enhance psychological health and physical activity and decrease screen time, I am particularly interested in psychological needs (e.g., competence, autonomy, and relatedness) and motivation as mechanisms for change. In a secondary line of research, I am interested in psychometrics and quantitative statistics.
