I am a radiologist specializing in oncologic body imaging. I have particular interest in cardiothoracic imaging, with a focus on detection and staging of thoracic malignancies. I am a member of the thoracic and cardiac disease management teams and also work as part of the lung cancer screening team.

My current research focuses on the assessment of lung cancers with specific genetic mutations using CT, on lung cancer screening, and on the use of CT to assess body composition in cancer patients. I am also actively involved in the interpretation of radiologic studies from patients enrolled in clinical trials to monitor treatment response.
