Summary
Andrea Baccarelli (often misspelled as Bakarelli) is an Italian-American epigeneticist and clinical endocrinologist, currently serving as the 10th Dean of the Harvard T.H. Chan School of Public Health since January 1, 2024. He is renowned for his pioneering research into how environmental factors, such as prenatal exposure to acetaminophen (Tylenol), can impact the human epigenome and contribute to neurodevelopmental disorders like autism and ADHD. His work, which explores scientific theories involving autoimmunity and the folate receptor, gained public attention when it was discussed on the All-In Podcast and cited by figures like Donald Trump and Bobby Kennedy in the context of autism causes.

- Autism researcher cited by Trump officials had testimony tossed out
Andrea Baccarelli, dean of the Harvard T.H. Chan School of Public Health, submitted written testimony in 2023 that his review of the scientific literature led him to conclude that prenatal exposure to acetaminophen, the active ingredient in Tylenol, “can cause the offspring to develop” neurodevelopmental disorders such as autism and ADHD. A Harvard spokesperson said that Baccarelli was paid roughly $150,000 for his work on the case. Advertisement
