About Me

I am a hematologist-oncologist specializing in the care of patients with leukemia. Along with other colleagues on the Leukemia Service at Memorial Sloan Kettering Cancer Center, I am dedicated to providing the best possible care by treating each patient as if he or she were a member of my own family.

As an active translational investigator, I have spent time both in the laboratory and in clinics to bring new and innovative treatments to patients with leukemia. I am particularly interested in developing more-effective and personalized therapies for patients with acute and chronic lymphoid leukemia, and am the lead investigator of a clinical trial using genetically modified T cells to treat patients with chronic lymphocytic leukemia (CLL). I am also a co-principal investigator on several other clinical trials in patients with acute lymphoblastic leukemia (ALL) and CLL.

My ultimate goal as a physician is to develop new and potentially curative therapies for patients with leukemia and to provide compassionate and individualized care to address each patient’s unique needs.

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.
