I am a medical oncologist and physician trained in both oncology and geriatric medicine who specializes in the care of patients with gastrointestinal cancers. I work closely with a multidisciplinary team of surgeons, radiation therapists, and other specialists to provide the best treatment and individualized care for each patient.  

My research focuses on improving treatment options for patients with these malignancies, particularly gastroesophageal cancers. As a board-certified geriatrican, I have a special interest in treating our older patients and studying how to better support them through chemotherapy and radiation. My research has been supported by the American Society of Clinical Oncology.

As well as seeing patients at Memorial Sloan Kettering’s Manhattan location, I treat patients at the West Harrison facility.  I am dedicated to providing compassionate, high-quality cancer care for all patients. 


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
