I am a hematologic-oncologist with a clinical and research interest in the use of cellular immunotherapy for the treatment of blood cancer. I am excited by the remarkable success of immunotherapy (a type of cancer treatment that uses a patient’s immune system to attack cancer cells in much the same way that it attacks bacteria or viruses) in people with different types of blood cancer.

One such example is a cellular immunotherapy called chimeric antigen receptor (CAR) T cell therapy. CAR T cell therapy involves removing immune cells (T cells) from the blood and introducing a new gene into those cells that enables them to recognize the cancer. After the gene is inserted, the T cells are infused back into the bloodstream, where they multiply and initiate a variety of immune responses aimed at attacking the cancer cells.

CAR T cell therapy is a rapidly expanding field. There are several FDA-approved CAR T cell therapies for people with blood cancer, and there are also numerous clinical trial options. Together with my colleagues in the Cellular Therapy Service, I focus on optimizing immunotherapeutic treatment strategies like CAR T cell therapy for people with leukemia, lymphoma, multiple myeloma, and other blood disorders.

I also care for patients who are admitted to Memorial Sloan Kettering Cancer Center to receive cellular immunotherapy treatment. My goal as a physician is to provide compassionate, personalized care that addresses each patient’s unique needs. To that end, I strive to not only create individualized treatment plans that honor patients’ priorities, but also to communicate clearly and openly with patients and their families. I am a big believer in patient-centered care, and patient care and safety are of the utmost importance to me.
