I am a board-certified hematologist and oncologist, and I am a member of a multidisciplinary team that cares for patients who are undergoing bone marrow transplantation. My particular expertise is using transplantation to treat patients with myelodysplastic syndromes and with acute myelogenous leukemia (AML) that has evolved from myelodysplastic syndromes. I am also interested in bone marrow failure syndromes including aplastic anemia and paroxysmal nocturnal hemoglobinuria. In an effort to improve the outcomes of patients undergoing transplantation, I design and monitor clinical trials of newer transplantation approaches.
