Physician Biography

I am a Pulmonary & Critical Care physician. Most of my patient care occurs within the hospital in the ICU. Another clinical area where I provide service is the InSight Tele-ICU which helps cover critical care units across the health care system at a central location. I also see outpatients with general pulmonary complaints in the Winchester Chest Clinic. I have a special interest in patients diagnosed with pulmonary embolus (clots in the lungs) and see patients in the Winchester Chest clinic after suffering from a Major Pulmonary Embolus, patients with inferior vena cava filters (IVC Filters), and patients suffering from pulmonary hypertension as a result of pulmonary embolus.

Yale has the ability to care for patients with advanced or complex Pulmonary diseases because of the expertise of its clinicians as well as its world class facilities. The collaboration amongst specialties is remarkable and combined with an emphasis on patient-centered care creates a progressive environment.
