The research in the lab focuses on: (1) Molecular pathways that regulate self-renewal and differentiation of hematopoietic stem cells (HSCs) and cancer stem cells, (2) Novel multi-target immunosuppressive approaches to treat immune-mediated Aplastic Anemia and bone marrow failure, (3) Characterization and mitigation of long-term effects of cancer chemotherapy on HSC function, hematopoiesis and immune system function, (4) Characterization and mitigation of acute and delayed effects of ionizing radiation on the hematopoietic system and HSC function, and (5) Characterization of molecular and cellular pathways regulating emergency hematopoiesis in response to bacterial and viral infections.
