Maiya R. Geddes, MD, FRCPC
Dr. Geddes is an FRSQ neurologist scientist and an Assistant Professor in the Department of Neurology and Neurosurgery at 成人VR视频. She听directs a research program at The Neuro within the Cognitive Neuroscience Unit and Brain Imaging Centre that focuses on motivational neuromedicine in aging. The goal of this highly translational program is to understand the neurobiological听mechanisms underlying motivational resilience and vulnerability in human aging and Alzheimer鈥檚 disease with the goal of helping older adults lead healthier and more fulfilling lives. 听Dr. Geddes鈥� research combines cutting-edge behavioural and multi-modal neuroimaging techniques including task-based and resting-state functional magnetic resonance imaging (fMRI). To translate her research findings, Dr. Geddes designs and leads novel intervention trials to enhance adherence to protective behaviours with the ultimate goal of dementia prevention. She leads a randomized controlled trial to enhance physical activity in older adults with a family history of Alzheimer鈥檚 disease that is jointly funded by the NIH and a 2023 Alzheimer Society Research Program New Investigator Award. Dr. Geddes is the recipient of the 2024 Brain Canada Future Leaders Award.
Dr. Geddes obtained an MD at the University of British Columbia, before completing a residency in adult neurology at 成人VR视频. She completed a CIHR-funded postdoctoral research fellowship at the McGovern Institute for Brain Research at the Massachusetts Institute of Technology supervised by John Gabrieli.听Dr. Geddes obtained subspecialty UCSN clinical fellowship training in behavioural neurology and neuropsychiatry at Harvard where she then joined the faculty in 2017, before returning to 成人VR视频 in 2019. Dr. Geddes鈥� research program was recognized with a Career Development Award from the American Neuropsychiatric Association and appointment as a Montreal Neurological Institute Killam听Scholar. Her research program is funded by the National Institute of Aging, the Canadian Institutes of Health Research, National Sciences and Engineering Research Council of Canada, Healthy Brains Healthy Lives, Fonds de Recherche du Qu茅bec - Sant茅, Brain Canada Foundation and the Alzheimer Society Research Program.
