About Me

What I Do at MSK
  • Attending Physician
Get To Know Me

I am a board-certified hematologist who specializes in caring for people with cancer who have disorders of the coagulation system. My expertise is in the evaluation and management of bleeding disorders or problems associated with abnormal clotting, and I work closely with the highly skilled surgeons at Memorial Sloan Kettering to ensure that patients with these disorders who need to undergo surgery do so safely without any complications.

People with cancer may develop abnormal blood clots. I work closely with the medical oncologists in all specialties to ensure that patients are treated safely and appropriately for blood clots while receiving cancer chemotherapy. Chemotherapy can often lower the blood counts such as white cells, red cells, and platelets. I also specialize in the evaluation and treatment of abnormalities in blood counts to allow patients to proceed with chemotherapy with minimal side effects related to low counts.

I am currently Chair of the Anticoagulation Quality and Safety Committee at MSK. My research interests include studying the optimal treatment and duration of treatment for cancer-associated thrombosis. I enjoy teaching and mentoring the next generation of physicians and was honored to receive the 2010-2011 and 2015-2016 Hematology Attending Teaching Award, selected by fellows from MSK’s Hematology/Oncology Fellowship program.

My Role at MSK

A hematologist-oncologist is a doctor who treats cancers of the blood. This doctor is a hematologist (HEE-muh-TAH-loh-jist) who diagnoses and treats blood disorders. They also are an oncologist (cancer doctor).
