Dr. Wang’s research focuses on the airway microbiome and virome, and their roles in asthma development and exacerbation. Her lab has established human cohort studies in the greater St. Louis metropolitan area to characterize the microbial communities in the upper or lower airway. Her lab has been working on the identification of functional bacterial and viral strains in asthma etiology. In addition, Dr. Wang has been leading a collaborative birth cohort study in San Juan, Puerto Rico, where they recruited infants who were exposed in utero to the devastating Hurricane Maria (2017 September) and collected infant nasal and stool samples for microbiome study. This study, entitled Hurricane as the Origin of Later Alterations in microbiome (HOLA), aims at understanding the impact of perinatal adverse exposures on the microbiome among offspring.
