About Me

My clinical expertise reflects an interest in lung cancer survivorship, but I am also interested in helping people who have incidental radiographic findings other than lung cancer. Many people who undergo chest x-rays or CT scans, for instance, learn that they have subtle abnormalities, such as small nodules, that are too small for biopsy.

While the vast majority of these abnormalities are not cancer, such findings still cause considerable anxiety when people know that there is something in the lung but don’t know what it is. For these people, I help decide which findings are suspicious and which are not. In doing so, I hope that those who have more worrisome findings can get their diagnosis efficiently and that others do not undergo any unnecessary tests or procedures.

I am interested in improving all phases of lung cancer management, including developing strategies for earlier diagnosis and guidelines to better manage symptoms among long-term survivors. With improvements in CT scanning and the advent of lung cancer screening, more and more people who have lung cancer are discovering their tumors earlier, when a cure with surgery is possible. For these people, I have worked with colleagues to create a lung cancer survivorship clinic.

Historically, lung cancer survivors have been an overlooked group of patients. Our lung cancer survivorship study group has been a national leader in describing challenges that survivors may face and what measures may be employed to manage them. We also intend to study medical and psychosocial problems that may develop in these patients, such as issues of sexual health, blame, stigma, and the fear of cancer recurrence.

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. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

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.
