George T. O’Connor, MD
Professor, Medicine
Biography
My research focuses on epidemiology, including genetic epidemiology, and clinical investigations of asthma, allergy, chronic obstructive pulmonary disease, and sleep apnea. I am currently a multiple PI and Co-director of the NHLBI’s Framingham Heart Study, and I am a co-investigator in the Risk Underlying Rural Areas Longitudinal (RURAL) Cohort Study. I am the Boston University-Boston Medical Center principal investigator of multiple NIH-funded multi-center investigations, including the All of Us Research Program, the Childhood Asthma in Urban Settings (CAUSE) consortium, and the Vitamin D Antenatal Asthma Reduction Trial (VDAART). I have led the BU-BMC site of clinical trials in children and adolescents with asthma and the Urban Environment and Childhood Asthma (URECA) birth-cohort study examining the risk factors for asthma and allergy in urban settings. l conduct epidemiologic and genetic epidemiologic research at the Framingham Heart Study, including genome-wide association studies seeking novel genetic determinants of lung function impairment, interstitial lung abnormalities, and atopy. My research spans disciplines including adult medicine, pediatrics, epidemiology, genetics and genomics, immunology, and environmental science. At Boston Medical Center, my outpatient practice focuses on adults with asthma, COPD, and bronchiectasis. I am an Associate Editor of JAMA.
