Gowthami Morey Arepally

Professor of Medicine

Gowthami M. Arepally, M.D. is a Professor of Medicine in the Division of Hematology at Duke University Medical Center and the Medical Director of Therapeutic Apheresis at Duke.  Her clinical interests are in immune thrombocytopenias, thrombotic disorders, and applications of therapeutic apheresis for immunologic disorders.    Dr. Arepally’s long-standing research program investigates immunoregulatory mechanisms in HIT.  Current laboratory efforts focus on the role of complement activation in the immune pathogenesis of HIT, investigations of protamine/heparin antibodies and development of murine models for studies of the HIT immune response.  Clinical projects include applications of therapeutic apheresis, including development of a multi-site network for investigations of thrombotic microangiopathy.
