Constandina Herbert, MN, RN, BMTCN is the Nursing Supervisor, Blood and Marrow Transplant Clinic at the Seattle Cancer Care Alliance/Fred Hutchinson Cancer Research Center. Ms. Herbert works with patients, families, and caregivers as they navigate the transplant process.

I am both a hematologist-oncologist and a clinical researcher. Along with caring for you, I conduct research focused on hematologic (blood-based) malignancies — specifically, acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), polycythemia vera, essential thrombocythemia and myelofibrosis. My overarching research aim is to help adults with these diseases have better outcomes by developing and testing evidence-based therapies that are tailored to your unique needs as a patient. I design and conduct clinical trials testing novel care concepts for people with AML and MDS, and I use

Dr. Kanwaldeep Mallhi is a pediatric oncologist and hematologist who specializes in nonmalignant blood disorders in children. These disorders include immunodeficiencies, bone marrow failure and metabolic errors. She is an expert in pediatric blood stem cell transplants, and her research focuses on alternative donor sources and the development of reduced-intensity conditioning regimens, which use radiation, chemotherapy or other procedures to remove diseased or failing cells prior to transplant.

Dr. Ivana Gojo is a Hematologist/Oncologist in Baltimore. Her clinical focus is on diagnosis and management of patients with acute leukemias (AML, ALL) and other myeloid malignancies (MDS, MPNs, CML), with emphasis on the development of novel therapeutic approaches for these diseases. She is nationally and internationally recognized expert in clinical translation of novel therapeutics for acute leukemias and principal investigator on multiple multi-center investigator-initiated studies. Dr. Gojo joined the Johns Hopkins faculty in 2012 as the Co-Director of Leukemia Drug Development Program

Dr. Shaffer is a board certified hematologist specializing in bone marrow transplantation for leukemia, myelodysplastic syndromes, lymphoma, and other bone marrow disorders. He works in a collaborative fashion with other members of our team to provide comprehensive cancer care at Memorial Sloan Kettering Cancer Center. His research focuses on the role of Natural Killer (NK) cells in outcomes after transplantation. NK cells are white blood cells that have anti-tumor and anti-infection properties. His goal is to improve the transplantation process for patients via understanding and optimizing NK

Dr. Niyongere joined the School of Medicine and Marlene and Stewart Greenebaum Comprehensive Cancer Center as an Assistant Professor in 2018. Her clinical focus is in acute leukemias, myelodysplastic syndromes, myeloproliferative neoplasms and bone marrow failure syndromes. Dr. Niyongere’s primary research interests are in finding new therapeutic targets by understanding oncogenic signaling pathways involved in AML and MDS as well as studying the role of the tumor microenvironment in the development of chemoresistance in leukemia. Dr. Niyongere also serves as an attending physician on the
