The LORD detests dishonest scales [analyzers] but accurate weights [calibrators] find favor with him." Proverbs 11:1

Biography

I grew up in Port Hope, ON where I attended Trinity College School. I then went on to the University of Toronto to study Chemical Physics. After my undergraduate training I attended the University of British Columbia Medical School and entered the UBC Medical Biochemistry Residency Training Program in 2001. Completing my residency in 2006, I joined the Department of Pathology and Laboratory Medicine at St. Paul's Hospital and have been Division Head of Clinical Chemistry there since 2008.  As of April 1, 2020, I became the Department Head.
