I am currently a postdoctoral researcher at the Image Processing lab at McGill University. I obtained my B.Sc. and M.Sc. in Electrical Engineering, Control Systems and my Ph.D. in Biomedical Engineering. My current research is focused on vascular causes of dementia in neurodegenerative disease populations (i.e. Alzheimer’s disease, Parkinson’s disease, and frontotemporal dementia). More specifically, I study white matter hyperintensities (which are the major MRI expressions of small vessel disease) and their effect on cognition.

Research Interests:

  • Medical image analysis
  • Machine learning and pattern recognition
  • Modelling, diagnosis, and prognosis
