Dr. Walker is a Clinical Neuropsychologist at the Ottawa Hospital and a Clinician Investigator with the Ottawa Hospital Research Institute where she has a research program evaluating cognitive health in multiple sclerosis. Her research focuses on cognitive fatigability, the cognitive impact of stem cell therapies, assessment and longitudinal evaluation of cognition, as well as the relationship between cognition and biomarkers of disease activity. She co-leads the Multiple Sclerosis Research Group and is on the Scientific Council of the University of Ottawa Brain and Mind Research Institute. She is an Assistant Professor of Medicine and an Adjunct Professor of Psychology at the University of Ottawa, as well as an Adjunct Research Professor with both Psychology and Cognitive Science at Carleton University. Dr. Walker completed an undergraduate degree at Queen’s University and received her PhD from the University of Windsor. She then completed a post-doctoral fellowship in rehabilitation neuropsychology at the Sister’s of Charity of Ottawa Health Service (now Bruyere Continuing Care). In her private practice, she provides neuropsychological assessments and co-leads a cognitive rehabilitation group for people living with multiple sclerosis.
