Richard F. Ambinder, M.D., Ph.D., currently serves as the James B. Murphy Professor of Oncology and the Director of the Division of Hematologic Malignancies at the Johns Hopkins Kimmel Cancer Center. He is program co-leader of the Hematologic Malignancies and Bone Marrow Transplantation Program and leads the AIDS Malignancy Consortium (AMC) site at Johns Hopkins and the AMC Translational Sciences Working Group nationally. Dr. Ambinder graduated from Harvard College with a Bachelor’s degree in biochemistry, after which he received his medical degree from the Johns Hopkins University School of Medicine before completing his residency at the Johns Hopkins Hospital. He also earned his Ph.D. in pharmacology from the Johns Hopkins University, and completed his oncology fellowship at Johns Hopkins. Within the clinic, Dr. Ambinder is active in the treatment of lymphoma and Kaposi’s sarcoma. Dr. Ambinder’s research is focused on exploring opportunities to prevent or treat cancer with viral infections. Virus-associated tumors are among the most common malignancies in certain populations and regions. For instance, Burkitt's lymphoma (EBV) and Kaposi's sarcoma (KSHV) are common in equatorial Africa, nasopharyngeal carcinoma (EBV) is common in southern Chinese populations or those with southern Chinese origins, and immunoblastic lymphomas (EBV) are common in immunocompromised patients (organ transplant recipients, AIDS patients, etc). Thus, Dr. Ambinder’s new approaches to prevention, diagnosis, and treatment stand to have a direct impact on the lives of cancer patients around the globe. Additionally, the study of how viruses can impact these tumors is important in creating model systems for the development of new approaches to cancer care. Currently, many immunotherapies target unidentified antigens, making the measurement of relevant immune responses problematic at best. However, in EBV-associated tumors the antigens are well defined, thus allowing the Ambinder lab to define the epitope-specific cellular immune responses. As a result of this breakthrough, interventions designed to alter immune response —whether they be vaccine based interventions, adoptive immunotherapy interventions, or pharmacologic interventions — may all be assessed in terms of relevant surrogate markers. Much in the same way the treatment of Hodgkin's lymphoma with radiotherapy and chemotherapy paved the way for the modern approach to cancer treatment more broadly, the treatment of EBV-associated tumors (including Hodgkin's lymphoma) may pave the way to the more generalized use of these modalities to treat a myriad of cancer types. Dr. Ambinder is rated as an Experienced provider by MediFind in the treatment of Reticulohistiocytoma. His top areas of expertise are Hodgkin Lymphoma, Non-Hodgkin Lymphoma, B-Cell Lymphoma, Tissue Biopsy, and Bone Marrow Aspiration.

As a physician scientist in the hematological malignancies and stem cell transplantation division with Sidney Kimmel Comprehensive Cancer Center at the Johns Hopkins, my focus is on the various aspects of cellular therapy in the treatment of hematological malignancies. My primary research focus is to develop strategies to prevent relapse of hematological malignancies following allogeneic stem cell transplantation. Additionally, I serve as the director of the adult CAR T program for hematological malignancies as we grow our CAR T program to help patients with advanced hematological malignancies. My academic interest in this space lies in studying the aspects of toxicity of CAR T cell therapy with an aim to improve long term outcomes in these patients. Among hematological malignancies, myeloproliferative disorders are my area of interest and I work to study newer drugs in early phase of development and also its treatment using allogeneic stem cell transplantation.

Dr. Zambidis is Associate Professor of Oncology and Pediatrics at the Johns Hopkins University School of Medicine, and a member of the Johns Hopkins Kimmel Cancer Center. Dr. Zambidis’ clinical expertise is in the treatment of disorders of the immune system, histiocytic disorders, hematologic malignancies, blood and bone marrow transplantation (BMT), and regenerative medicine. His research interest focuses on advancing our understanding of pluripotent stem cells– the ‘master’ stem cells that can generate any new cell or tissue that the body needs to repair itself. Dr. Zambidis earned his M.D./Ph.D. in the Medical Scientist Training Program at the University of Rochester, Rochester, N.Y. He completed his Pediatrics Residency in the Department of Pediatrics, Washington University, St. Louis, Missouri, and his clinical/research fellowships in Pediatric Hematology/Oncology at the Johns Hopkins Hospital and the National Cancer Institute at the NIH. Dr. Zambidis has been interested in the biology of stem cells since he came to Johns Hopkins, in 2001. As a Pediatric Hematology/Oncology fellow, he was one of the very first Hopkins investigators to work with human embryonic stem cells (hESCs), beginning shortly after they were made available to the biomedical research community, in 2002. Dr. Zambidis was awarded the first NIH K08 Clinician-Scientist Training Award specifically investigating the therapeutic potential of human pluripotent stem cells (2004). After joining the Hopkins faculty, in 2005, he developed an experimental model of the early formation process of human blood and blood vessels using human pluripotent stem cells. The Zambidis laboratory at the Johns Hopkins Institute for Cell Engineering focuses on understanding the developmental biology of human hemato-vascular and human pluripotent stem cells. More recently, his group completed studies on highly efficient methods for generating nonintegrated, human induced pluripotent stem cell (hiPSC) lines from myeloid progenitors. His group has developed novel hiPSC-based vascular therapies for retinopathies, and more recently derived a new class of human pluripotent stem cells in a naïve ground state with new functionalities with even greater potency and stronger regenerative capacities. As a BMT physician-scientist, his long-term goal is to use hESC, hiPSC, and related pluripotent stem cell technologies to not only treat severe degenerative diseases, but also to elucidate the biological nature of cancer and aging.
