My research focusses on investigating the associations between environmental and occupational exposures and a number of adverse health outcomes.  Specific projects include evaluating the impacts of long-term exposure to air pollution and the risk of chronic diseases such as cancer, diabetes and dementia.  I also study the health benefits of urban greenness which include how these features of the built environment help promote physical activity, and reduce the risk of mortality, and adverse birth outcomes.   My research activities have also investigated the impacts of urban greenness in reducing harmful exposures of air pollution, noise, and urban heat island.  My graduate students have participated in these research activities by conducting field work, and also working with large administrative health datasets. I am currently leading a study that is characterizing the risk of lung cancer in a cohort of Newfoundland miners who were occupationally exposed to radon.


websiteMy substantive area of expertise is in the fields of epidemiology, biostatistics and environmental health. I am currently a Professor in the School of Mathematics and Statistics, while holding appointments in the Department of Health Sciences and in the Departments of Health Sciences and Neurosciences at Carleton University. I am also an Affiliate Scientist at the Ontario Occupational Cancer Research Centre in Toronto, and an Associate Editor for the journal Environmental and Occupational Medicine. I also continue to serve as an on the Advisory Committee for the Canadian Health Adaptations, Innovations, and Mobilization (CHAIM) Centre at Carleton (

As I will be on sabbatical between July 1, 2019 and June 30, 2020 I am not accepting new applications for students at this time.  I will consider applications for students with an interest in applied statistics, environmental health and epidemiology for September 2020.

Students who have an interest in joining my research team are encouraged to provide a letter of interest outlining their specific research interest, and current curriculum vitae.
