Overview
As a diagnostic hematopathologist and molecular genetic pathologist, my clinical interests are focused on the histologic examination of tissue and bone marrow biopsies to diagnose hematologic malignancies (leukemia, lymphoma, myeloma, etc.) as well as testing DNA from tumors or from blood to detect inherited or acquired mutations that can guide therapeutic management and predict clinical outcome. My research interests involve 1) understanding the biology of T-cell and NK-cell neoplasms; 2) defining the immunomodulatory response to neoplastic disease; 3) developing methods to monitor immune response and thereby refine tumor immunotherapy; and 4) exploring novel applications of tumor genetics in the diagnosis, prognosis, and management of cancer.
