Abstract: Children spend the majority of their day in school and school attendance is mandatory. Exposures to microbes in the indoor built environment, both pathogens and non-pathogens, impact the health of occupants in both positive and negative ways. This talk will focus on the measurement of indoor bacterial, fungal, and viral exposures in elementary schools using molecular techniques including metagenomics sequencing, and the discussion of environmental factors that influence exposure, and health implications.

Her research group performs clinical and translational research at the intersection of environmental exposures, the human microbiome, and lung disease. Her work is supported by grants from the National Institutes of Health, the American Lung Association, the American Thoracic Society, and a Transformative Scholars Award from the MGH Department of Medicine.
