Dr. Richard Deth is Professor of Pharmacology at Nova Southeastern University and Professor Emeritus at Northeastern University. His research interests are focused on the role of oxidative stress and impaired methylation reactions in neurodevelopmental, neuropsychiatric and neurodegenerative disorders. In recent years his work has focused on understanding the factors contributing to the autism epidemic. This ongoing work includes investigations of the status of vitamin B12, the influence of gluten and casein-derived opioid peptides on redox and methylation status, and the role of neuroinflammation.
