As a pulmonologist I care for patients with diseases of the lungs, some of whom are already undergoing treatment for cancer. I see the majority of my patients in our Pulmonary Outpatient Clinic or by consultation.

My work with patients over the years has raised many interesting research questions. Among them is what to do with small abnormalities, such as lung nodules, that are found by accident among patients who have lung-imaging scans for other reasons. Most of these turn out to be benign, but they are understandably major sources of anxiety to patients.
