Research and Scholarly Activity

Professor Dubin's 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 derivatives and lags of the curves. He is also interested in change point models for longitudinal data.

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.

Professor Dubin works in a variety of application areas, including nephrology, cancer, smoking cessation, aging, environmental issues, and the analysis of adverse events from clinical trials.

Biography

After completing his Masters degree in Applied Statistics at Villanova University in 1993, Professor Dubin worked at Veteran Affairs Health Services and Research in Houston, Texas; and at the University of Texas M.D. Anderson Cancer Center, also in Houston.

He then went on to receive his PhD in Statistics from the University of California at Davis in 2000, after which he worked as an Assistant Professor at the Yale University Department of Epidemiology and Public Health in the Division of Biostatistics, forging several collaborations with researchers in public health and medicine at Yale, some of which continue today.

He arrived as an Associate Professor at the University of Waterloo in 2005, with a joint appointment in the Department of Statistics & Actuarial Science, and the Department of Health Studies & Gerontology.
