Myelodysplastic Syndromes (MDS)

Tiffany N. Tanaka, MD, is a board-certified hematologist specializing in the diagnosis and treatment of blood cancers and blood disorders, with an emphasis on myeloid malignancies. Dr. Tanaka is a translational researcher who focuses on the development of early phase trials that offer new cancer treatments for patients. Her research work includes the study of epigenetic and genetic biomarkers in myelodysplastic syndromes (bone marrow disorders in which the bone marrow does not produce enough healthy blood cells), with the aim of translating these into clinical therapies to improve patient care

Dr. Tamari is a board-certified hematologist and oncologist specializing in the use of stem cell transplantation to treat patients with hematologic malignancies (cancers that arise from blood cells). She works as part of a multidisciplinary team of transplantation specialists who treat patients with these diseases. As a clinical researcher, Dr. Tamari's work focuses on identifying risk factors associated with relapse after allogeneic stem cell transplantation for myelodysplastic syndrome and acute muyelogenous leukemia. Together with her colleagues she is developing protocols for early post

Dr. Tabbara has researched blood and bone marrow stem cell transplant. He established the bone marrow transplant program at The GWU Medical Center in 1992 and has performed several hundred stem cell transplants treating patients with leukemia, lymphoma, multiple myeloma and myelodysplastic syndrome. Additional areas of interest for Dr. Tabbara are breast and lung cancers. He has served as the director of the medical thoracic oncology program at GWU since 2003.

Angela Smith joined the Department of Pediatrics in July 2008 in the Division of Hematology/Oncology/Blood and Marrow Transplantation and became Director of the Division Blood and Marrow Transplantation in 2019. Dr. Smith graduated with her medical degree from the Medical College of Wisconsin in 2002. She then went on to complete her internship and residency in Pediatrics at the University of Minnesota. Following residency, she completed a fellowship in Pediatric Hematology/Oncology/Blood and Marrow Transplantation at the University of Minnesota in June 2008. During her fellowship, she also

Robert Siegel, MD is board-certified in Internal Medicine, Medical Oncology, and Hematology. He is a professor with The George Washington University School of Medicine & Health Sciences.

Dr. Siegel returned to GW as a faculty member in 1982, was promoted to associate professor in 1989 and full professor in 2000. Upon returning to GW, he spearheaded the

Dr. Shereck specializes in bone marrow transplantation for children with cancer, blood disorders and immunodeficiencies. She conducts clinical trials as a part of the Primary Immune Deficiency Treatment Consortium (PIDTC) and the Pediatric Blood and Marrow Transplant Consortium (PBMTC). Dr. Shereck is also interested in discovering innovative ways to teach the next generation of physicians. She has plenty of opportunities to try out new models of learning through the medical school course she teaches (Blood and Host Defense) and as the fellowship director for pediatric hematology/oncology.

Dr. Josh Sasine is a hematologist and oncologist at UCLA specializing in the treatment of hematologic malignancies, including hematopoietic stem cell transplantation (bone marrow transplantation), cellular therapy, and clinical trials of novel therapeutics. He is the Director of the Chimeric Antigen Receptor T-Cell (CAR T) Program. He treats patients with blood and bone marrow disorders such as leukemia, myelodysplastic syndrome, lymphoma, multiple myeloma, amyloidosis, aplastic anemia, Waldenstrom Macroglobulinemia, polycythemia vera, primary myelofibrosis, paroxysmal nocturnal hemoglobinuria
