Research Interests
Ravi Kalhan, MD, MS is Director of the Northwestern Asthma and Chronic Obstructive Pulmonary Disease (COPD) Program where comprehensive care is provided to patients with asthma and COPD at all stages of severity. Dr. Kalhan additionally serves as medical director of the lung volume reduction program leading the multidisciplinary evaluation of patients for both bronchoscopic and surgical approaches to severe COPD. Dr. Kalhan attended college at Brown University in Providence, RI where he majored in modern American history. He subsequently entered medical school at Case Western Reserve University School of Medicine and completed his internal medicine residency at the Hospital of the University of Pennsylvania. He then came to Chicago where he pursued his fellowship training in Pulmonary and Critical Care Medicine at Northwestern Memorial Hospital, and has been on the Northwestern faculty since 2006. Dr. Kalhan's clinical interests are in the care of patients with both asthma and COPD. His research interests relate to respiratory epidemiology, in particular identification of early risk factors that impact the vulnerability of some individuals to develop chronic respiratory disease. He is also involved in clinical trials of new therapies for both asthma and COPD.
