    Education:

    B.S.   Chemistry, Purdue University, West Lafayette, IN, 1970 - 1974

    Ph.D.   Analytical Chemistry, Purdue University, West Lafayette, IN, 1974 - 1979



    Research Interests:

    - Research Overview
    I engage in the following research activities:
    1. The proper approach to and science behind the evaluation of clinical laboratory methods.
    2. Investigation of novel biomarkers for diagnosis and monitoring of disease.
    3. Method development and evaluation of clinical laboratory technology for new applications, and for diagnostic reagent and instrument companies.



    Clinical Focus:

    I serve as Director of Clinical Chemistry, Toxicology, and Point-of-Care Testing at Grady Memorial Hospital. My particular interests include the cost-effective utilization of laboratory medicine for patients with diabetes, cardiovascular problems, and toxicology applications, as well as the reduction of non-analytical sources of error. I am currently Secretary of the National Academy of Clinical Biochemistry.
