Murray Potter



Professor and Chair,

Department of Pathology and Molecular Medicine, Division of Clinical Pathology

Associate Member, Department of Pediatrics, Division Head - Genetics and Metabolics

Research Interests

The major focus of my research is on inborn errors of metabolism/biochemical genetics. This encompasses clinical research in the treatment of these disorders and the development of diagnostic tests, particularly the development and clinical validation of mass-spectrometry based assays.


I spend most of my clinical time in the area of biochemical genetics, either running Metabolic Genetic clinics at McMaster Children's Hospital, or directing the Biochemical Genetics Laboratory at the Hamilton Regional Laboratory Medicine Program. I am also head of the regional newborn screening follow-up program and member of the Newborn Screening Ontario Advisory Council.

Academic Interests

I primarily teach post-graduate trainees in laboratory medicine and pediatrics residency and fellowship programs. I am also an active member of the national governing bodies for medical biochemistry (Royal College of Physicians and Surgeons of Canada) and biochemical genetics (Canadian College of Medical Geneticists).
