Dr. Gagnon earned her PhD. in Clinical Psychology at Laval University (Quebec City) with a specialization in Neuropsychology. Her clinical training includes neuropsychological assessments and interventions. Her Ph.D. research focused on the neural basis of human memory which she has studied using brain stimulation.

Dr. Gagnon’s interest for human memory and non-invasive brain stimulation has led her to move to Boston, Massachusetts, to train and teach at Harvard Medical School. She has published on the topic and has been invited to give talks and lectures in French and in English on this topic.
She completed her clinical residency in Clinical Neuropsychology at London Health Science Center (LHSC) in London, Ontario where she worked with a variety of adult patients presenting with a wide array of memory disorders (e.g. acquired brain injuries, early dementia, epilepsy, etc). During that time, she also wrote about diagnostic issues and early detection of cognitive changes in an aging population : Gagnon, I. Gutmanis, K. Hansen, S. Woolmore-Goodwin, J. Wells, M. Borrie, J. Fogarty (2013) in Canadian Journal of Neurological Sciences. 40(5):678-83.
She then moved to Toronto to complete a post-doctoral fellowship in Geriatric Psychiatry at the Center for Addiction and Mental Health (CAMH & University of Toronto) where her work as a neuropsychologist enabled her to expand her skills in neuropsychological assessment and pursued her career as part time staff neuropsychologist in in CAMH`s memory clinic. Aside from her work at the hospital, Dr Gagnon was also teaching at the University of Toronto a course entirely dedicated on Human Memory, and ran a small private practice, with offices downtown Toronto and in Markham (GTA).
She moved to Montreal in 2013, to pursue her interest for academia and grow in a Clinician-Scientist career in her birth city, Montreal. In her current research and clinical work she is striving to refine her clinical skills, clinical knowledge, to teaching students, to give talks and trainings, lead and/or support research projects from colleagues at the Douglas Institute and McGill University.
