After his medical residency at Massachusetts General Hospital in Boston and heme/onc fellowship at Memorial Sloan Kettering Cancer Center, he joined the Adult Bone Marrow Transplantation Service of MSKCC where he serves as an Assistant Attending.  He studies how the intestinal microbiota interact with the host immune system as it relates to hematopoietic stem-cell transplantation, with a particular interest in graft-vs-tumor activity and graft-vs-host disease.

Research Interests:

My research is focused on the mechanisms by which commensal bacteria modulate alloimmunity, both with respect to graft-vs-host disease (GVHD) and to graft-vs-tumor activity. My long-term research goals include developing microbiota-based biomarkers that will be clinically useful in the care of transplant recipients, as well as microbiota-targeted therapeutic strategies to improve patient outcomes.
