      Collapse Overview
      My research interests are in the areas of clinical chemistry, toxicology and pharmacogenetics. In the area of clinical chemistry, we are involved in translational research studies aimed at the clinical evaluation of novel biomarkers or biomarker panels to diagnosis, treat and monitor disease. In toxicology, my research is centered on the use of mass spectrometry to detect small molecules in human samples. Our research studies are focused on uncovering trends in drug misuse and drug adulteration and understanding the clinical implications of these trends. We are also involved in the development and implementation of new mass spectrometry methods and technologies, such as high resolution mass spectrometry, in the clinical laboratory. In the area of pharmacogenetics, we are interested in understanding how genotype influences an individual’s susceptibility to adverse drug reactions and drug-induced toxicity.
