Clinical Interests

Dr. Bacharier is Professor of Pediatrics and Medicine at Washington University School of Medicine, USA Clinical Director of the Division of Pediatric Allergy, Immunology and Pulmonary Medicine, and Unit Co-Leader for the Pediatric Patient Oriented Research Unit. He received his undergraduate degree in biophysics from The Johns Hopkins University, USA and his medical degree from Washington University School of Medicine. Dr. Bacharier was an intern and resident in pediatrics at St. Louis Children's Hospital and a fellow in Pediatric Allergy and Immunology at Children's Hospital, Boston and Harvard Medical School. He was a recipient of the 2005 Samuel R. Goldstein Leadership Award in Medical Student Education from Washington University School of Medicine and is a member of several organizations including the American Academy of Allergy, Asthma and Immunology, the American College of Allergy, Asthma and Immunology, and the American Thoracic Society. Dr. Bacharier's research focuses on childhood asthma. Specifically, he is a Principal Investigator in the NHLBI-funded AsthmaNet, a multi-centered network examining therapeutic approaches to childhood asthma. He is an investigator in the NHLBI’s Severe Asthma Research Program (SARP) and the Inner City Asthma Consortium’s URECA study examining the influence of urban environments on the development of asthma and allergic disorders. He is also an Investigator in the American Lung Association’s Asthma Clinical Research Center Network. Dr. Bacharier is also currently investigating the role of early infection with Respiratory Syncytial Virus upon the subsequent development of asthma.
