A physician and scientist with over 40 years of experience in medicine and biomedical research. For the past 15 years, he has focused on uncovering the biological causes of autism and developing therapies based on identifying chronic infections, inflammation, and immune system dysfunction. His approach has helped more than 1,000 children with autism across multiple countries. He believes that many forms of autism can be alleviated—or even reversed—when we treat the underlying biological causes rather than just the symptoms.
