Biography
In 1977 Dr. Brown received a Ph.D. in clinical psychology from Wayne State University. He was an Attending Staff Psychologist in the Neuropsychology Division at Henry Ford Hospital from 1977 to 1994. In 1994 he became Staff Psychologist at The New York Hospital. Dr. Brown is currently Chief of the Psychology Service at the VA San Diego Healthcare System, where he has worked since 1995. Dr. Brown serves as Associate Director of Clinical Neuroscience at the UCSD Center for Functional MRI and Co-Director of the VA/UCSD Laboratory of Cognitive Imaging. He is an ABPP/ABCN Diplomate in Clinical Neuropsychology.

Research Focus
Dr. Brown’s research uses computational modeling and brain imaging methods to investigate neuropsychiatric disorders. His laboratory makes use of functional, structural, and metabolic brain imaging to investigate the etiology and clinical course of neurological and neuropsychiatric disorders, especially schizophrenia. The laboratory’s imaging studies focus on the development of brain imaging methods and their application to clinical problems. The laboratory’s computational modeling involves the use of both parametric and connectionist models to analyze neurobehavioral impairments in patient populations. The laboratory uses Parametric Modeling Measurement theory to integrate theoretical models of cognition with psychological test construction theory.

Clinical Focus
Dr. Brown’s clinical work involves the use of neuropsychological tests to assess neurobehavioral functioning in patients at risk for neurological or psychological disorders.
