Dr. Ellen Freeman

Biography

Ellen Freeman is an associate professor in the School of Epidemiology and Public Health with a cross appointment in the Department of Ophthalmology. 

Dr. Freeman received her PhD in epidemiology from the Johns Hopkins School of Public Health in the United States in 2005 where she trained with Dr. Sheila West in the field of ocular epidemiology.  During Dr. Freeman’s training, she was a recipient of a 4-year training award from the National Institute on Aging.  After completing her PhD, she did a post-doctoral fellowship at the University of Michigan.  Dr. Freeman then spent 9 years at the Université de Montréal where she was the recipient of two salary awards from the Fonds de Recherche en Santé du Québec.

Dr. Freeman’s research program focuses on the epidemiology of eye disease and vision loss.  She currently is the principal investigator of a 5-year grant from the Canadian Institutes of Health Research looking at the cognitive effects of age-related eye disease in a cohort of over 400 patients.  She is also examining issues related to vision loss and aging in the Canadian Longitudinal Study on Aging, a cohort of over 30,000 people. 

Dr. Freeman has published widely including papers in leading ophthalmology and aging journals.
