Research Interests:

Human cancer immunology and immunotherapy, transplantation immunology

Allogeneic hematopoietic stem cell transplantation represents the most powerful approach to cure human hematological malignancies through the graft-versus-tumor (GVT) effect, although it is often associated with a complication of graft-versus-host disease (GVHD). The long-term goal of my research is to identify molecular targets recognized by donor T cells for segregating GVT from GVHD using cellular immunology and molecular biology approaches. Currently there are two major research themes in my laboratory. One theme is to investigate adoptive donor T cell therapy for leukemia and lymphoma. Under this aim, we are testing if the Sleeping Beauty (SB) transposon system, a mobile DNA, can mediate long-term therapeutic gene expression in human primary T cells for the treatment of refractory leukemia. The other theme is to identify and characterize GVT and GVHD associated antigens including leukemia stem cell antigens and minor histocompatibility antigens. With this information, we will be able to track antigen-specific T cells in transplant patients and develop strategies to augment GVT and prevent GVHD.
