Lab name: Aging, Cerebrovascular, and Neurodegenerative Disorders

Theme-Based Group: Aging, Cognition, and Alzheimer’s Disease
Division: Human Neuroscience


My team aims to investigate the role of cerebrovascular pathology in aging and neurodegenerative disease populations. My research program has three main components:

  1. Developing neuroimaging and machine learning tools to accurately detect and track signs of cerebrovascular and neurodegenerative pathologies
  2. Investigating the relationship between cerebrovascular and neurodegenerative pathologies, the impact of lifestyle and environmental factors on these diseases, and the impact of cerebrovascular pathology on clinical outcomes in neurodegenerative disease populations
  3. Ex-vivo assessment of cerebrovascular disease using post-mortem MRI and histology

Mahsa Dadar, PhD, received her Bachelor’s and Master’s Degrees in Electrical Engineering from the University of Tehran and Concordia University, and her PhD in Biomedical Engineering from McGill University. She did a postdoctoral fellowship with the International Progressive MS Alliance (IPMSA) team at McGill, followed by a joint postdoctoral fellowship between the CERVO Brain Research Centre in Quebec and the University of Alberta in Edmonton, Canada.
