Get to Know Me

I am a board-certified medical oncologist who specializes in treating patients with gastrointestinal cancers. I have a special interest in caring for patients with an inherited risk for colorectal cancer.

I work very closely with a team of surgeons, oncologists, gastroenterologists, and radiation therapists to provide the best treatment and care for each patient.

In addition, I have a separate genetics clinic where I provide clinical counseling and genetic testing for people who may have an inherited predisposition to gastrointestinal or other cancers. Based on genetic test results and family history, I help men and women with cancer incorporate genetic information into their treatment plan and the surveillance of cancer after treatment.

My research focuses on the discovery of novel cancer-susceptibility genes and the development of new approaches to cancer screening and prevention in high-risk families. I have received an American Society of Clinical Oncology Career Development Award, and more recently was honored to be selected for a Clinical Investigator Award by the Damon Runyon Cancer Research Foundation for my research on the genetic causes of cancer in patients with early-onset disease. 

Through funding secured via the National Institutes of Health, I am also studying genetic susceptibility in patients who have more then one malignancy. I am an active member of the American Society of Clinical Oncology and recently served as chair of its education committee on cancer genetics.

What I Do 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.

A clinical geneticist is a scientist with special training in diagnosing and treating genetic conditions. They can help explain your risk of getting a genetic condition that is passed on from parents to children.
