Dr. Mackenzie is Professor of Pathology and Laboratory Medicine at The University of British Columbia, Consultant Neuropathologist of Vancouver Acute and BC Cancer Agency, and Head of the Neuropathology Division at Vancouver Acute.

Dr. Mackenzie has broad expertise in neuropathology and the use of brain tissue banks in the care of patients with neurological disorders. His research program centers on neuropathology and the molecular genetics of neurodegenerative disease, particularly dementias. He is currently the Canadian representative to the International Society of Neuropathology and is an editorial board member for a number of neuropathology journals.
