    RESEARCH INTERESTS

    Dr. Yeh's research interests are in the areas of preclinical and clinical
    pharmacokinetics, drug metabolism, drug interaction, drug delivery and
    biopharmaceutics. The projects include determination of the physical and chemical properties of a therapeutic entity, method development and validation of sensitive and specific analytical techniques for the identification and quantitation of new chemical entities and/or drugs and their metabolites in biological matrices, characterizing the in vivo pharmacokinetics and metabolism of new chemical entities and/or drugs using animal models, scaling preclinical and in-vitro data to predict events in humans for preliminary assessment of safe exposure levels, determination of the metabolite profiles of drug candidates using hepatocytes and liver microsomes containing a single enzyme, identify Phase I or Phase II enzymes responsible for metabolite formation, predict drug interactions due to inhibition or induction of drug metabolizing enzymes, regulation and function of drug-metabolizing enzymes, particularly with an interest in elucidating mechanisms of drug-drug, herb-drug and food-drug interactions and studying the role of drugs and natural products in drug induced hepatotoxicity and in cancer chemotherapy, development of intravenous and extravascular dosage formulations for synthetic organic molecules to optimize their therapeutic values, and improving the drug delivery system of drugs through the use of novel formulations (i.e. micro-and nanoparticles) to help localize the drug to target sites and minimize drug toxicity.

    RESEARCH ACTIVITIES & ACCOMPLISHMENTS

    Dr. Yeh is currently involved in the early stage new small molecular entities discovery at Division of Biotechnology and Pharmaceutical Research (DBPR). He has contributed to help DBPR drug discovery team to the success of several discovery projects leading to the selection and/or termination of development candidate(s) from the pharmacokinetics and drug metabolism aspects. A significant portion of his present and previous researches has been to develop novel assay methods and formulations to evaluate pharmacokinetic properties and drug metabolites of the small chemical entities and drugs, and to integrate the in vitro and in vivo correlation to extrapolate into human clinical trials.
