I am a medical oncologist whose practice is dedicated to caring for people with gastrointestinal cancers. These include colon cancer, rectal cancer, and appendiceal cancer. I also have expertise in treating hepatobiliary cancers. I specialize in systemic chemotherapy, where the treatment circulates throughout the body, and regional chemotherapy, meaning the drug is delivered directly to the liver or abdomen. I see patients at MSK’s Rockefeller Outpatient Pavilion, in Manhattan.

The goal of my research is to develop new, more-personalized therapies for people with colorectal and hepatobiliary cancers. For example, we are working to develop immunotherapy and molecular-based approaches to effectively treat these diseases. I have a particular interest in advancing our understanding of colorectal cancers at the molecular level so that we can learn how and why they grow and spread.

As a medical student unsure of the exact path my career would take, my family was impacted by cancer. The journey that followed influenced me both in terms of my career choices and goals, and also how I care for patients today. My experience being on the other side of the consultation desk helped me to understand and appreciate what patients and their families go through after receiving a cancer diagnosis.

When caring for my patients, I aim to provide the best evidence-based treatments and to surround them with compassion. I place a great deal of emphasis on communication to help reduce their distress and maximize their quality of life.
