About Me

I am a hospitalist who is focused on providing high-quality medical care, with an emphasis on quality of life and relief of suffering. Throughout my training as a medical resident at Columbia Presbyterian Hospital, I developed a profound appreciation not only for the complex medical problems that develop in people with cancer, but also for the distinct psychosocial aspects of cancer care. Influenced by my interest in this unique, intricate balance, I joined Memorial Sloan Kettering as a hospitalist. Humanism and a patient-centered approach are essential to the doctor-patient relationship and have become tenets of my clinical practice. 

My main priorities at MSK are centered on clinical care, research, and medical education. My principal role as a nocturnal physician is admitting patients and providing initial diagnosis, work-up, and treatment of a wide range of medical and oncologic ailments. My colleagues and I are responsible for inpatient subspecialty consults at night, including cardiology and nephrology, and serve as the leaders of rapid response teams for people who are critically ill. We play an integral role at the Josie Robertson Surgery Center, providing overnight comprehensive care for people after surgery, including preoperative assessment, pain and fluid management, and evaluation of postoperative complications. I emphasize evidence-based care in my practice of inpatient medicine. I participate in continuing medical education activities and conferences to update my medical knowledge and have completed specialized training, including bedside echocardiography, to advance my diagnostic skills.

I have participated in a variety of research activities at MSK, including clinical research exploring the impact of recurrent exposure to intravenous contrast on renal function over time. I am involved in quality-improvement projects that aim to improve the frequency and quality of communication of goals of care at hospital admission. Equitable patient care regardless of race, ethnicity, religion, gender, gender identity, or sexual orientation is extremely important to me, and I seek to explore related issues and their effect on patients’ health outcomes.

Education of our transitional-year interns and rotating residents is also a high priority in the Hospital Medicine Service at MSK. I serve as a supervisor and educator for these new physicians and emphasize a holistic approach to cancer care — not only the necessity to learn the pathophysiology and science behind a patient’s diagnosis and treatment, but also the need to understand the patient’s personal priorities, particularly in end-of-life situations.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicare and New York State Medicaid also provide benefits for care at MSK.
