I was raised and educated in BC including completion of my MD and Medical Biochemistry residency training. I have worked at St. Paul's Hospital since 2009 and have enjoyed working in this patient focused chemistry lab where I spend 70% of my time, as well as at Vancouver General Hospital where I have a weekly clinic treating adult patients with inborn errors of metabolism. I was selected as the BCALP Chair of the Chemistry science section till 2019.

Academic Background

• MD, UBC 1997

• Medical Biochemistry, UBC 2003

Expertise / Research Interests

I have been co-investigator for a number of research projects involved with inborn errors of metabolism, including mitochondrial disease, alpha 1 antitrypsin deficiency, and IgG4 related disease.

Teaching Interests

I have been the medical biochemistry residency training program director since 2004 and have finished my term as of 2015. I am also the vice chair for the national specialty committee.
