    Research Interests:

    - Transplantation Immunology
    My main interest focuses on the clinical implications of donor specific HLA antibodies in renal transplant recipients.



    Clinical Focus:

    Dr. Robert Bray and I co-direct the HLA laboratory that provides histocompatibility testing for transplantation. My clinical focus revolves around increasing allocation of deceased donor kidneys to highly sensitized patients awaiting renal transplantation. My approach is to accurately identify and define HLA antibodies in such patients.
