About Me

I have been on the faculty of Memorial Sloan Kettering since 1989, and over the years I have treated thousands of people with common as well as rare gastrointestinal cancers. I have particular expertise in managing cancers of the colon and rectum, as well as rare tumors of the digestive tract such as carcinoid and pancreatic neuroendocrine tumors, and other digestive tract cancers such as liver, pancreas, stomach, and esophagus cancers. I also treat other neuroendocrine tumors such as adrenal cancers and pheochromocytomas.

Much of my career has also been dedicated to developing new drug therapies and treatment strategies for colorectal cancer, and I have tapped the vast resources of Memorial Sloan Kettering — from various clinical departments to the Human Oncology and Pathogenesis Program, the Sloan Kettering Institute, and The Rockefeller University — to create an integrated translational research program.

I served as Chief of the Gastrointestinal Medical Oncology Service for 5 years. I am Chair of the hospital’s Pharmacy and Therapeutics Committee and co-leader of the Colorectal Disease Management Team. I am also a Professor of Medicine at Weill Cornell Medical College.

Nationally, I serve on the National Cancer Institute (NCI) Rectal and Anal Cancer Task Force and am co-leader of the Alliance NCI Cooperative Research Group efforts in colon and rectal cancers. I also serve on three National Comprehensive Cancer Network (NCCN) guidelines committees: colorectal cancers, neuroendocrine cancers, and unknown primary cancers.

Since 1990 I have authored or co-authored more than 150 peer-reviewed journal articles on the development of new treatments for colorectal and other gastrointestinal cancers. I have also written numerous books, book chapters, monographs, and reviews on current and future treatment strategies for these diseases.

I am honored to have received various teaching and research awards over the years, as well as recognition for my work from such organizations as the American Cancer Society (Career Development Award) and Gilda’s Club (Advancement of Cancer Medicine Award).

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.
