I am working on strategies to enhance immune reconstitution and graft-versus-tumor
activity after hematopoietic stem cell transplantation (HSCT). My main focus is on T and
NK cell reconstitution, developing strategies based on adoptive transfer of in vitro
generated lymphoid precursor cells into syngeneic and allogeneic HSCT recipients.
