Epidemiology and Biostatistics

Mona Izadnegahdar, PhD


Dr. Izadnegahdar completed her PhD degree in Epidemiology at the University of British Columbia, School of Population and Public Health and her Master degree in Epidemiology at the University of Calgary, Department of Community Health Sciences, Faculty of Medicine.

Dr. Izadnegahdar’s main research interests include cardiovascular epidemiology, quality of life, access to care and in particular, understanding the contributing factors to the poor outcomes and health status of younger adults following a heart attack. Her doctoral thesis examined sex differences in outcomes of younger adults following a heart attack and was supported by the Canadian Institutes of Health Research Frederick Banting and Charles Best Doctoral Award and the Canadian Cardiovascular Outcomes Research Team (CCORT).

Over the last 10 years, she has developed expertise in the area of cardiovascular research, working at the Centre for Health Evaluation and Outcomes Sciences, the Providence Health Research Institute and Cardiac Services BC.
