Research Overview

Dr. Mansbach has been performing multicenter bronchiolitis and respiratory virus research with the Emergency Medicine Network ( over the past decade.  He has been Principal Investigator, Co-Investigator, or site Principal Investigator of multiple industry, foundation, and NIH grants. Currently, Dr. Mansbach is Co-Investigator and on the Steering Committee for a NIH-funded multicenter study following 1,000 children hospitalized with bronchiolitis for the development of recurrent wheezing and eventual asthma. He is also actively investigating the influence of the nasopharyngeal microbiome and 25-hydroxyvitamin D levels on the severity of a child’s bronchiolitis illness.

About Jonathan Mansbach, MD, MPH

Dr. Mansbach graduated from Haverford College and Duke University School of Medicine before coming to Boston Children’s Hospital as an intern. He has been at Boston Children’s Hospital ever since. He completed a hospitalist and adolescent medicine fellowship, and now spends the majority of his time investigating bronchiolitis and respiratory viruses. He obtained a Masters of Public Health from the Harvard School of Public Health.
