I am a hematologist/oncologist, Director of the MSK Center for Hematologic Malignancies at Memorial Sloan-Kettering Cancer Center (MSK) and a Member of the Human Oncology and Pathogenesis Program at MSK. My clinical expertise is in myeloid malignancies, chronic lymphocytic leukemia, and rare blood cancers including hairy cell leukemia, chronic myelomonocytic leukemia, and histiocytoses. My research is focused on understanding the genetic alterations in patients with these cancers. One of our main areas of interest is understanding the role of mutations in RNA splicing factors and developing means to target cells with these mutations therapeutically.
