Dr. Dahiya is a cancer specialist with board certification in internal medicine, hematology, and medical oncology. He is an Associate Professor at Stanford University School of Medicine and Clinical Director of Cancer Cell Therapy in the Stanford BMT and Cell Therapy division.

Dr. Dahiya strives to support each patient with a personalized and compassionate care plan that optimizes healing and quality of life.

Prior to joining Stanford, Dr. Dahiya was an associate professor of medicine at the Greenebaum Comprehensive Cancer Center at the University of Maryland School of Medicine, where he developed the Cellular Immunotherapy Program and served as the Director of Cellular Immunotherapy in leukemia and lymphoma.

Dr. Dahiya’s research focuses on cellular immunotherapy for hematologic malignancies. He has led and participated in several investigator-initiated studies and sponsored clinical trials with cell therapies (CAR-T, CAR-NK, TCR-T) for hematologic malignancies. His research group is also involved in various translational research activities for the standard of care and research CAR-T therapy. Dr. Dahiya’s group was the first group to show the role of fibrinogen in Neurotoxicity associated with CAR-T therapy. They showed vascular injury as manifested by high fibrinogen levels is associated with higher Neurotoxicity in patients who receive CAR-T therapy. More recently his group led a novel study of assessing the immune response to COVID-19 disease. They evaluated the immune response in critically ill and non-critically ill patients hospitalized with COVID-19 disease and showed a differential immune response between the groups. Dr. Dahiya’s group also showed and established poor immunogenicity of COVID-19 vaccines in CART recipients. As such, passive immunity and other strategies to address the issues of immunogenicity are being explored.

He has published more than 50 articles in peer-reviewed journals including the New England Journal of Medicine, Journal of Clinical Oncology, Blood, Blood Advances, Lancet, Leukemia Research, Neuro-Oncology, and many more. He reviews article submissions for the journals Critical Reviews in Oncology and Hematology, Thoracic Cancer, and Blood. He serves as the hematology lead editor for the journal Critical Reviews in Oncology and Hematology.

He has presented his research findings at conferences such as the annual meetings of the American Society of Hematology, American Society of Clinical Oncology, and American Society for Transplantation and Cell Therapy.

Dr. Dahiya is a member of the American Society of Hematology and the American Society of Transplantation and Cell Therapy.
