I am a fellowship-trained radiologist who specializes in oncologic body imaging. I have a special interest in cardiothoracic cancers and I am experienced in interpreting body CT, cardiac MRI, and ultrasound. At Memorial Sloan Kettering, I am a member of the Thoracic and Cardiac Disease Management Teams. I work closely with my colleagues across many departments to ensure our patients receive comprehensive, coordinated care. I am also part of the lung cancer screening team.

In addition to my clinical duties, my current research interests include enhancing multimodality imaging techniques for lung cancer and cardiac tumors. I am also actively enrolled in clinical trials that monitor patients’ responses to treatment.


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
