Research interests

As Director of the ARCH Lab in the School of Public Health and Health Systems at the University of Waterloo, my research focuses on advancing the understanding of youth multimorbidity—the co-occurrence of physical and mental disorders in children, youth, and young adults. My work takes a developmental approach to estimating the burden of youth multimorbidity and the extent to which prevalence is sample-dependent, as well as expounding the multilevel determinants of youth multimorbidity; biological (systemic inflammation) and psychosocial (family environment) mechanisms leading to the onset of youth multimorbidity; and, through data linkage activities, how youth with multimorbidity interface with the mental health care system. I aim to bridge the clinical-epidemiological divide by conducting both clinical and population-based studies to prevent youth multimorbidity, improve youth health, help families, and enhance care and reduce health system costs.

Methodologically, I'm interested in the measurement of mental health and quality of life in youth, particularly those with chronic health conditions. In addition to validating the factor structure of measures, I examine the extent to which measures of mental health and quality of life are equivalent across different groups. In other words, I empirically test whether the underlying construct of a measure is interpreted similarly across groups; hence, potential group differences can be interpreted as meaningful, and not an artifact of differential interpretation.
