With more than 20 years of experience in clinical biochemistry, with the last 15 years in biochemical genetics. Trained in basic biochemical genetics (Laboratory diagnosis) in Sydney, Australia and holds a PhD from University of Adelaide, Adelaide, Australia for research done on lysosomal storage disorders (Metachromatic leukodystrophy). Research interest includes genotype/phenotype correlation study for disorders in Inborn Errors of Metabolism (IEM), molecular genetics. Have a keen interest in method development and application of tandem mass spectrometry in the detection and screening for inherited disorders and  other related health sciences
