Physician Scientist Training Program



David Schwartz, MD is the former Robert Schrier Chair of Medicine and Director of the Physician Scientist Training Program at the University of Colorado. He has made numerous contributions toward understanding the role that biological and genetic determinants play in the onset of diseases that are influenced by the environment. These efforts have provided new insights into the genetics, epigenetics, and genomics of interstitial lung disease, asthma, and innate immunity. His work has led to the recognition that genetic susceptibility, and specifically MUC5B, plays a role in the etiology of pulmonary fibrosis.  Dr. Schwartz’s lab was the first to clone the human TLR4 gene and demonstrate that variation in this gene decreased immune responsiveness to endotoxin, enhanced the risk of Gram negative sepsis, and protected individuals from the development of coronary artery disease. In addition, the Schwartz lab demonstrated the importance of locus-specific DNA methylation in the development of allergic airway disease by directing the maturation of T lymphocytes toward a Th2 phenotype. He is a member of the American Society for Clinical Investigation, the Association of American Physicians, and the American Clinical and Climatological Association, and a recipient of the American Thoracic Society Scientific Accomplishment Award and the Amberson Lectureship Award and the Bonfils-Stanton Science and Medicine Award.
