Research & Publications

Research Summary

Amaris Keiser’s research interests are in perinatal epidemiology and health disparities. As the evolving literature examining birth outcomes increasingly recognizes their multifactorial nature, Dr. Keiser seeks to understand the complex interactions between genetics, environmental context, maternal age and racial/ethnic background that drive both outcomes and disparities. She has been examining trends at the population level through analyses using a statewide database from California, focusing first on preterm birth, and with plans to extend the analyses to examine both low birth weight and small for gestational age births. In addition, she is using the Boston Birth Cohort to explore associations between maternal prenatal and perinatal exposures and the risk of infant necrotizing enterocolitis, and understand the extent to which these associations vary by race/ethnicity.
