Dr. Mari DeMarco is a Clinical Chemist at St Paul's Hospital, the Research Director for Providence Health Care, and a Clinical Professor in the Department of Pathology and Laboratory Medicine at the University of British Columbia in Vancouver, Canada.

As part of her PhD thesis, Dr. DeMarco explored protein misfolding pathways and focused on the pathological mechanisms (misfolding, aggregation and replication) in human prion diseases. This interest in amyloidosis and neurodegeneration carried over to her clinical work, where she leads the development and implementation of new diagnostics for neurodegenerative disorders like Alzheimer's disease, frontotemporal dementia, Parkinson's disease and dementia with Lewy bodies.

Reflecting her research group’s accomplishments and those of the incredible staff working in Clinical Chemistry Lab at St. Paul’s Hospital, Dr. DeMarco is the recipient of the University of British Columbia’s Early Career Excellence in Research and Discovery, the American Association of Clinical Chemist’s Outstanding Scientific Achievements by a Young Investigator award, MSACL’s Bereman Award for Innovative Clinical Proteomics and the Award for Research Excellence from the Canadian Society of Clinical Chemists.
