Katharine C. Hsu, MD, PhD

About Me

I am a medical oncologist and hematologist who cares for people with bone marrow disorders, leukemias, lymphomas, and certain types of solid tumors. I specialize in allogeneic (donor provided) bone marrow and stem cell transplants. My research focuses on the biology of the natural killer cell, a white blood cell with antitumor behavior, and its role in affecting the outcome of transplants. A major goal of my research is to determine how natural killer cells can be used to improve the treatment of cancers.

Clinical Trials

Research is integral to our mission at Memorial Sloan Kettering, and clinical trials help us discover better forms of patient care and treatment. For you, this could mean access to a new therapy or therapy combination. Click to see a list of the trials I’m currently leading.


Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
