Brief Biography

Mary Corey is a Senior Scientist in the Hospital for Sick Children Research Institute and Professor at the University of Toronto in Departments of Public Health Sciences, Paediatrics, and Health Policy, Management and Evaluation. Dr. Corey created the comprehensive Toronto CF database, which is central to a multi-disciplinary approach to CF that has been praised as a model of bench-to-bedside research. Her research has focussed on statistical models to explain the extreme variability of disease in CF, and the complex interactions between multiple genetic and environmental factors that cause disease in general. She has served as consultant to national CF data registries in Canada and several other countries. Dr. Corey is a founding member of the Genetic Statistics Group at the University of Toronto which has been awarded a National Centers of Excellence award for developing new statistical methods for human genetics research (1999-present). Dr. Corey's research is also funded by the Canadian Cystic Fibrosis Foundation (1977-present), the US National Institutes of Health (1989-present), and Genome Canada (2002-present).

Research Interests

  • Epidemiology of cystic fibrosis
  • Genetic epidemiology of complex traits

Research Activities

Although cystic fibrosis (CF) is a classic genetic disease, the severity and progression of symptoms are extremely variable.

My research is focused on explaining this variability in the regional Toronto CF Database and the Canadian CF Patient Data Registry. Survival analysis shows the relative risks associated with many factors like sex, mode of diagnosis, pancreatic function, lung function, and infection. Longitudinal regression analysis defines the rate of decline in lung function and its relationship to other factors, including CF mutation categories, as well as other genes that may modify CF severity.

These studies produce the knowledge necessary to develop and assess new treatments for CF, and provide a model for studying other complex genetic diseases.
