    Research Interests:

    - Hemostasis
    Complications of Pregnancy & Reproduction Dr. Duncan and his staff have identified several profiles that identify patients at higher risk for problems and in particular have recognized that a particular analyte Lipoprotein (a) has a much higher frequency in this population and may be an important predictor of future pregnancy problems. As a result of this work on infertility patients he has devised a protocol now used by all major IVF groups in Atlanta in which LMW heparin is started prior to embryo transfer and this has apparently improved the pregnancy success rate. He believes the whole infertility and early pregnancy failure area offers significant opportunity for further study on the involvement of the hemostasis system in diagnosis and monitoring of these patients in the first trimester.
