About Me

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

I am an internist who provides overnight care for hospitalized patients at Memorial Hospital.

My role involves managing a range of conditions, from pain and infections to complications related to cancer treatments, medications, or ongoing protocols. I work closely with patients who are receiving cancer care and address any urgent medical needs that arise during their stay and ensure continuity of care.

It is both an honor and a privilege to serve the Memorial Sloan Kettering Cancer Center (MSK) community, and to support patients through their treatment journey with compassionate, comprehensive overnight care.

In additional to my clinical responsibilities, I am passionate about pancreatic cancer research. I’ve contributed to several projects exploring risk factors for pancreatic cancer. My work has highlighted significant metabolic changes that occur in the lead-up to cancer development.

As a bilingual and biracial physician, I am proud to offer culturally sensitive care to the diverse MSK community. My daily goal is to advocate for my patients both in and outside the hospital. I am also deeply committed to medical education and enjoy teaching residents during night shifts, where I engage in bedside teaching and guide them through complex clinical scenarios.
