Board Certifications

Internal medicine; Hematology; Medical Oncology

I am a board-certified medical oncologist trained in both hematology and medical oncology. My focus is on caring for people with lymphoma who are admitted to the hospital. I oversee the care of people who have recently received a lymphoma diagnosis, patients needing lymphoma therapy in the hospital setting, and those who have been admitted for any other reason associated with their lymphoma. I work closely with the entire team of lymphoma specialists, both within the Department of Medicine and across other departments. At MSK, we emphasize this team approach in order to provide the best care for our patients. My goal is to make your hospital stay as pleasant, seamless, and stress-free as possible.
