Internal Medicine

As a hospitalist at Memorial Sloan Kettering, I care for people with all types of cancer who have been admitted to the hospital for medical issues such as infection, organ failure, side effects of chemotherapy, and cancer-related emergencies. As the patient’s primary physician overnight, I strive to provide patient-centered care while creating a comprehensive medical treatment plan and ensuring a safe and seamless transition of care to the patient’s primary day team. My responsibilities also include supervising and teaching resident physicians training at MSK, and providing clinical support to advanced practice providers (nurse practitioners and physican assistants).

In addition to my clinical work, I am interested in quality improvement and patient safety within the hospital setting to ensure we continue to provide our patients with streamlined, high-value care within increasingly complex hospital systems.
