I am a Professor of Statistics in the Department of Statistics and Actuarial Science at the University of Waterloo and hold cross-appointments at the School of Public Health and Health Systems at the University of Waterloo and the Faculty of Health Sciences at McMaster University. From 2005 to 2019, I held a Tier I Canada Research Chair in Statistical Methods for Health Research, and I am now a Mathematics Faculty Research Chair.

I completed a BSc in Statistics at McMaster University, and a Master's in Mathematics and a PhD in Statistics at the University of Waterloo. My research interests include the analysis of life history data, the design and analysis of clinical and epidemiological studies, and statistical methods for incomplete data. Areas of collaboration in health research include autoimmune disease, transfusion medicine and public health research more broadly.

I welcome enquiries from strong students interested in graduate studies or post-doctoral fellowships.
