Overview

My research focuses on clinical applications of mass spectrometry, including the development of plasma and urine amino acid methods for diagnosis of inborn errors of metabolism.

I am actively involved in the validation of new technologies and assays for use in biochemical genetics and newborn screening laboratories.
