Research interests

Toxicology, Pharmacology, Biochemistry, Biomedical applications of accelerator mass spectrometry.

My research includes characterizing the low-dose pharmacokinetic, metabolism, and tissue distribution properties of toxicants and potential drug leads using accelerator mass spectrometry in an effort to understand their mechanisms of action.  We are also using a pharmacogenomics approach to understand inter-individual susceptibility to adverse drug reactions. We are also studying the toxic and/or carcinogenic effects of small molecules in subcellular, cellular and animal models to determine how these effects relate to human cancer susceptibility.   We are also developing a novel platform, using nanolipoprotein particles, to enhance the metabolism and elimination of chemical toxicants.
