About Me

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

I am a board-certified medical oncologist who specializes in caring for people with liver cancer, gallbladder cancer, and bile duct cancer, as well as other gastrointestinal cancers. My primary goal is to provide the best possible treatment and individualized care for people with these diseases. I work closely with a team of surgeons, radiation oncologists, and other medical professionals who specialize in the diagnosis and treatment of gastrointestinal cancer.

In my research, I am trying to find new, effective therapies for gastrointestinal cancer, particularly primary liver and bile duct tumors. For example, I am working on ways to use a patient’s own immune system to fight cancer, which is called immunotherapy. In addition, I am investigating strategies to block specific cellular pathways that cancer uses to grow. I have developed and am leading numerous national and international clinical trials of these new cancer therapies for patients with liver, bile duct cancers, and other solid tumors.

I am also focused on improving how we conduct clinical research with patients and increasing access to clinical trials. To this aim, I am a standing member of the Institutional Review Board, which is the committee that approves all clinical research at Memorial Sloan Kettering. I am also part of several other executive committees aimed at improving the conduct of clinical trials.    

My research and training has been supported by the American Society of Clinical Oncology, the National Comprehensive Cancer Network, the National Institutes of Health, the American Association for Cancer Research, and the Howard Hughes Medical Institute.  My work has been published in the New England Journal of Medicine, Nature, Nature Medicine, the Journal of Clinical Oncology, Cancer Discovery, Clinical Cancer Research, and Cancer.

My Role at MSK

A gastrointestinal (GAS-troh-in-TES-tih-nul) medical oncologist is a cancer doctor who specializes in gastrointestinal (GI) cancers. This includes anal, colorectal, esophageal, gastric (stomach), liver, and pancreatic cancers, as well as GI stromal tumors and neuroendocrine tumors.

An early drug development specialist tests new drugs to treat cancer. They have special training in research studies, known as clinical trials.
