My primary research interest is in the area of methodological development in longitudinal data analysis, including for multivariate longitudinal data, where more than one outcome, (e.g., systolic and diastolic blood pressure) are each followed for individuals over time. Methods pursued for this type of data include the correlation of different longitudinal outcomes over time using curve-based methods, and incorporating lags and derivatives of the curves. I am also interested in change point and latent response models for longitudinal data, as well as prediction models.
An additional area of interest is developing graphical methods for censored survival data, which simultaneously display individual-level as well as cohort-level survival information. This research has resulted in two separate graphical methods, the event chart and the event history graph; the latter displays time-dependent covariate information embedded within the Kaplan-Meier survival curve.
I work in a variety of application areas, including nephrology, cancer, smoking cessation, aging, environmental issues, and the analysis of adverse events from clinical trials.
Along with Professor Joon Lee in the University of Waterloo School of Public Health & Health Systems, I am the co-leader of the Health Data Science Lab.
