Pulmonary, Critical Care and Sleep Medicine 

Our Mission

Our mission is to improve the lives of patients with critical illness, disorders of the chest, lungs and airways, and disorders of sleep. We strive to do this through extraordinary and personalized patient care, world-class education, and innovative research.

Clinical Care

Our clinical programs and services include inpatient (in-hospital) and ambulatory (clinic-based) care. Our physicians and other team members always aim to provide high quality and compassionate care.  

Medical Education

Our educational programs include world-class fellowships for physicians seeking advanced training in pulmonary, critical care or sleep medicine. As a major teaching hospital for Harvard Medical School and the home of an exceptional Internal Medicine Residency Program, our faculty teach and lead programs for medical students and medical residents, both in the classroom and at the bedside. All of the major Harvard Medical School courses related to respiratory physiology and pathophysiology are taught and directed by our members. We also offer CME programs for physicians and other healthcare providers. 

Biomedical Research

Research is a vital part of the Division. Our members have funding from the National Institutes of Health to study basic mechanisms of disease pathogenesis and the clinical expression of those diseases. Clinical research focuses on medical ICU outcomes, and the utility and efficacy of various interventional procedures. Basic laboratory investigations seek to define the mechanisms of pathogen recognition by lung macrophages in the context of host defense function, identifying the roles of critical innate immune receptors in directing and regulating specific host cell innate immune responses. Physiologic investigations examine the nature of the sympathetic nervous system response to hypoxia, and the mechanisms and behavioral factors underlying breathing discomfort. Ongoing human and animal studies address mechanisms of altered cardiovascular control in sleep apnea and the neurocognitive consequences of sleep apnea and sleep deprivation. Investigators also provide in-depth training in the methods and approaches of biomedical research to train future scientists.
