From Dec 2024: Dr. Kristen Lyall, Sc.D., on Autism, Pregnancy & Environmental Risk Factors — From the Spectrum: Finding Superpowers with Autism

Originally released in December 2024, this conversation is being re-released as part of a selection of guest interviews from the podcast archive.

In 2025, she was awarded a $2 million NIH research grant as part of the Autism Data Science Initiative, one of 13 funded projects selected from more than 250 applications.

We discuss how epidemiologists investigate autism risk, the interaction of genetic and environmental influences, prenatal nutrition, folic acid, fish consumption, omega-3 fatty acids, and exposure to environmental chemicals. Dr. Lyall explains how large-scale studies, including the NIH's ECHO program, help researchers identify patterns while navigating the important distinction between association and causation. Our conversation explores what the evidence suggests, what remains uncertain, and how this research may inform maternal and child health.
