Dr. R G. Barr

Dr. Barr’s research focuses on respiratory epidemiology with a focus on chronic obstructive pulmonary disease (COPD) and emphysema. In particular, he is interested in a better understanding of the causes of emphysema and COPD subtypes and uses machine learning to integrate advanced imaging (computed tomography [CT] and magnetic resonance imaging [MRI]) with multi-omic measures in large cohorts. He is principal investigator for the Multi-Ethnic Study of Atherosclerosis (MESA) Lung Study, the longest-running prospective study of emphysema on CT; the SPIROMICS Heart Failure Study, a large study of cardiopulmonary interactions using state-of-the-art echocardiography and MRI; a related study of deep-learning on CT scans; and the C4R CT Harmonization Study, which is harmonizing quantitative lung CT measures on CT scans from approximately 30,000 participants in 10 cohorts.

His clinical expertise encompasses Cerebral Hypoxia, Harding Ataxia, Spastic Ataxia Charlevoix-Saguenay Type, and Pol 3-Related Leukodystrophy.

Dr. Barr is board certified in Internal Medicine. He is actively involved in clinical research, co-authoring 5 peer reviewed articles. Dr. Barr is currently accepting new patients.
