  • Division of Clinical Chemistry, Vancouver General Hospital
  • Regional Medical Leader for Clinical Chemistry, Vancouver Coastal Health


Morris Pudek trained in Clinical Chemistry at VGH, following his PhD in Biochemistry from UBC, and obtained his certification from the CSCC in 1979. Morris served on the first board of directors of the Canadian Academy of Clinical Biochemistry and was the first recipient of the CACB award for outstanding service to the profession of Clinical Biochemistry. At the present time he is the Medical Leader for Clinical Chemistry for Vancouver Coastal Health. In addition he is a Clinical Professor in Pathology at UBC. Morris is the author or co-author of approximately 100 scientific publications. He has received many teaching awards from residents, science students and medical students over the years.
