Neil Flomenberg, MD, is an accomplished researcher whose work has been supported by grants from the National Cancer Institute, Dr. Flomenberg's research interests center on ways to make allogeneic transplants (using a donor, rather than the patient's own stem cells) safer. In addition, he is also working to try to prevent deadly graft-versus-host-disease (GVHD), the bane of marrow and peripheral blood progenitor cell transplants, and hopes to find ways to increase immune system recovery after allogeneic transplant. These efforts have opened up opportunities for successful transplantation of patients lacking a well matched donor.
A recipient of numerous teaching and research awards, Dr. Flomenberg received the prestigious Service to Mankind Award from the regional Leukemia & Lymphoma Society in 2006 and in 2003, he was named the Leukemia & Lymphoma Society's Man of the Year for Eastern Pennsylvania.
