Pharmacoepidemiology Diabetes Pharmacy Practice Medication Adherence
I received my BSP from the University of Saskatchewan and completed a hospital pharmacy residency at the Regina General Hospital. After working as a hospital pharmacist for a few years, I returned to school and completed a PharmD (University of Toronto) and MSc (University of Alberta). I joined the Faculty in 2004 and teach in the areas of evidence based medicine (primarily focusing on critical appraisal of observational trials) and endocrine (primarily focusing on diabetes management).
My research can be categorized into two major areas.
Health Outcomes Research
I am interested in understanding the effects of medications used to treat people with type 2 diabetes. My work in this area follows three lines of inquiry:
- Is there an association between sulfonylurea use and risk of adverse cardiovascular events?
- Does aspirin dose moderate the effect of aspirin in people with type 2 diabetes?
- How does medication adherence affect the association between medications and outcomes in people with type 2 diabetes?
I have used a number of research methods in the fields of pharmacoepidemiology and systematic reviews to examine these questions.
Health Services Research
I am interested in understanding the effects of pharmacist intervention in the management of people with type 2 diabetes.

Pharmacy 343 (Pharmacotherapy 2)
This course is designed to help undergraduate pharmacy students develop fundamental knowledge of fluid and electrolyte imbalances, laboratory values, as well as renal, urinary tract, and endocrine conditions.
March 30, 2023: I am actively seeking applications for an MSc trainee position to begin in September 2023. The successful applicant will learn to apply standard pharmacoepidemiologic methods to examine the association between drug exposure and health outcomes.
I am actively seeking applications for an undergraduate research assistant for the summer (May to August). the successful applicant will help with operation of an ongoing study run in community pharmacies.
Students will develop fundamental knowledge of fluid/electrolyte imbalances and laboratory values, as well as renal, urinary tract, and endocrine conditions. They will apply therapeutic and pharmaceutical science knowledge to various patient care scenarios. Students will further develop their critical thinking and self-directed learning skills, along with their breadth and depth of therapeutic knowledge, as they incorporate principles of evidence-based therapeutic decision making within the patient care process framework. (Restricted to Pharmacy students.)
