In 1987, he transitioned from an NIMH research fellow under Richard Wyatt to Chief of the Clinical Brain Disorders Branch.[8] In 1995, Weinberger became a clinical professor of psychiatry and behavioral sciences at George Washington University.[9] In 2011, Weinberger became the CEO of the Lieber Institute for Brain Development in Baltimore, Maryland.[10] In 2012, Weinberger became a professor of psychiatry, neurology and neuroscience at the McKusick-Nathans Institute of Genetic Medicine, and the Johns Hopkins University.[11]
Work
Weinberger is most known for his work on identifying genetic factors and biochemical mechanisms in mental illness, and promoting research in these areas to further explain causes behind disorders such as schizophrenia. He is the original author of the landmark neurodevelopmental hypothesis of schizophrenia (first published in The Neurology of Schizophrenia, Elsevier, 1986)[12] and in the more cited reference, Arch Gen Psychiatry 1987, (the most cited publication [>4100 citations] about the biology of schizophrenia in Google Scholar).[13]
[7] He is an expert in the neurobiological mechanisms of genetic risk for developmental brain disorders, such as the gene that codes for catecho-O-methyltransferase (COMT), the enzyme that breaks down the chemical messenger dopamine.[14] Weinberger discovered that a tiny variation in this gene slightly increases risk for schizophrenia, a discovery which Science Magazine ranked as the second most important scientific breakthrough of 2003.[14][15] In a later paper, he analyzed the activity of the gene Neuregulin-1 in a large collection of brain samples from schizophrenic patients and found that the regulation of the gene contributes to schizophrenia.[16]
In a review in Neuron, Weinberger wrote that individuals of African ancestry must be included in research for brain illnesses.[17] In studies of brain disorders, individuals of African descent make up, on average, less than 5% of research cohorts.
He has published over 800 papers in peer-reviewed journals,[18] and has written for The Hill[19] and The New York Times.[20]
He maintains columns on mental health at the Huffington Post,[21] Medium,[22] and The Conversation.[21]
