Modifiable Autism Risk Factors Research Program

The Modifiable Autism Risk Factors research program seeks to identify and better understand the mechanisms behind exposures or behaviors that can contribute to an increased risk of autism spectrum disorder (ASD). Researchers use methods ranging from epidemiology to exposure biology to investigate risk factors for autism that aren’t inherited. Initiatives include large-scale collaborative projects focusing on child health as well as a range of innovative studies that examine environmental exposures such as maternal dietary factors and prenatal exposure to chemical mixtures. Program faculty collaborate regularly with an extensive network of leading autism researchers locally and worldwide to pioneer novel methods of exploring autism risk at a population level.
