Anissa Abi-Dargham, MD, is the Director, Division of Translational Imaging, New York State Psychiatric Institute (NYSPI), and Professor of Clinical Psychiatry (in Radiology) at Columbia University. Her research utilizes molecular imaging techniques (SPECT and PET) to study the pathophysiology of schizophrenia, schizophrenia related spectrum disorders and addiction. Her work has resulted in seminal publications describing the complex alterations of dopamine transmission in schizophrenia and their relationship to clinical symptoms, cognition and response to treatment, as well as their interrelatedness to glutamate dysfunction in schizophrenia. These studies showed increased striatal dopamine release in schizophrenia, which has become one of the most established findings of schizophrenia research and is now being tested as a biomarker for risk to develop schizophrenia in prodromal patients. She has many published scientific articles and book chapters.
