R. Graham Barr, MD, DrPH

Principal Investigators

Dr. Barr’s research is in respiratory epidemiology with a focus on obstructive lung disease and emphysema. In particular, he is interested in a better understanding of the epidemiology and causes of these components of chronic lower respiratory disease using methods that integrate advanced imaging (predominantly computed tomography [CT] and magnetic resonance imaging [MRI]) with genomic, cellular and biomarker information in large cohorts. Currently, Dr. Barr is principal investigator for the Multi-Ethnic Study of Atherosclerosis (MESA) Lung Study, a related genetic study and the MESA COPD Study, and the Columbia University Field Center for SubPopulations and Intermediary Outcome Measures in COPD Study (SPIROMICS), and COPD Gene study. He is also principal investigator for the Spirometry Reading Center for the DPP-OS and LLFS.
