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.  Her clinical interests are in immune thrombocytopenias, thrombotic disorders, and complement-mediated diseases.  Dr. Arepally’s long-standing research program investigates the immune pathogenesis of heparin induced thrombocytopenia (HIT).  Current laboratory efforts focus on the role of complement activation in antibody production and thrombosis in HIT, studies of complement inhibitors for immune-complex mediated diseases and diagnostic biomarkers of platelet activation.

Research Interests

Our laboratory conducts translational studies of hematologic disease. Using heparin induced thrombocytopenia (HIT) as a model disease, we apply in vitro, ex-vivo and in vivo approaches to uncover disease mechanisms, model disease and apply discoveries to patient care. Beyond HIT, our laboratory is investigating biomarkers of venous thrombosis and HIT, complement's role in other immune-complex disorders and mechanisms of classical pathway regulation.
