Current Position

 

Associate Professor, Department of Medicine, University of Alberta

Director, Hypertension Clinic, University of Alberta

 

Research Areas

 

I have a background in general internal medicine, clinical pharmacology and clinical epidemiology. I am an academic internist and a health services researcher with an interest in cardiovascular risk management.  Specific areas of interest include primarily bariatric (obesity) care and hypertension addressing care-gaps. 

 

Research Goals

 

I am a physician, epidemiologist and health services researcher, with expertise in clinical pharmacology, general internal medicine and clinical epidemiology. I specialize in the care of adult patients with complex, multisystem disease, including (but not limited to) hypertension and other chronic cardiovascular diseases. I am the Director of the University of Alberta Hypertension Clinic and the Co-Chair of the Canadian Hypertension Education Program Recommendations Task Force. A large part of my research focuses on bariatric (obesity) care delivery in Canada.

 

Current Research Activities

 

a. Leading a 500-patient CIHR-funded prospective observational study (APPLES) examining the clinical, economic and humanistic (satisfaction, health-related quality of life) ramifications of protracted wait times for bariatric surgery.  This study involves a comparison of medically-treated, surgically-treated and wait-listed patients.

 

b. Leading a CIHR-funded study that aims to identify potential prioritization indicators for bariatric surgery (OASIS study).

 

c. Leading a CIHR-funded RCT examining the effectiveness of community-based education for obesity in reducing weight and preparing patients for bariatric intervention (EVOLUTION study).

 

d. Coinvestigator in an RCT examining the efficacy of pharmacist-led case management in improving blood pressure and lipid control in patients who have experienced a stroke or TIA.

 

e. a Site Lead for industry-sponsored clinical trials in obesity and hypertension.
