About Me

I am a board-certified thoracic surgeon who specializes in caring for people with cancers of the chest. These include primary and metastatic tumors involving the esophagus, lung, mediastinum, airway, pleura, and chest wall. I have expertise in esophageal and tracheal diseases in particular. I also care for patients with a variety of benign conditions related to these areas such as gastroesophageal reflux, high-grade Barrett’s dysplasia, hiatal hernia, achalasia, esophageal diverticula, and tracheal stenosis. Whenever possible, I use minimally invasive techniques to perform lung and esophageal surgery with very small incisions to allow for a smoother and faster recovery for patients. I operate at Memorial Hospital in Manhattan, and I see patients at both Rockefeller Outpatient Pavilion, also in Manhattan, and MSK Rockville Centre on Long Island.

My mission is to provide a personalized treatment plan that is specifically tailored to each individual patient’s needs. Patients, as well as their family members, caregivers, and primary care providers, are all integrated into the decision-making process. I also strive to offer patients access to the latest innovations and treatment options while working closely with my colleagues in medical, interventional, and radiation oncology.

In addition to my clinical work, I lead a research effort in collaboration with the Marie-Josée and Henry R. Kravis Center for Molecular Oncology focused on discovering new therapeutic targets and markers of disease progression in esophageal cancer. Our goal is ultimately to develop more-precise tools for diagnosing, staging, and predicting response to treatment in esophageal cancer patients. I am also involved with clinical trials of targeted and immunotherapy for esophageal cancer, which represent promising areas of advancement in the field.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time.

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. Medicaid and New York State Medicare also provide benefits for care at MSK.
