Jack A. Elias, M.D., the Waldemar Von Zedtwitz Professor of Medicine and chair of the Department of Internal Medicine, delivered the J. Burns Amberson Lecture at the American Thoracic Society International Conference in May. The lecture is given by individuals who have made major lifetime contributions to pulmonary research or clinical practice. Elias studies the cellular and molecular biology of processes related to lung injury and repair. His work established current concepts of the inflammatory mechanisms of lung diseases, including asthma, chronic obstructive pulmonary disease (COPD), acute lung injury, and pulmonary fibrosis.
