Biological Methods

This report presents a study led by Tanya L. Alderete, a recipient of HEI’s 2019 Walter A. Rosenblith New Investigator Award, at Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland. Alderete and colleagues examined whether prenatal or postnatal exposures to air pollution were associated with changes in the infant gut microbiome and fecal metabolome during the first 2 years of life.
