Biography

Dr. Light received his PhD from the SDSU/UCSD Joint Doctoral Program in Clinical Psychology with a specialization in Neuropsychology in 2001. After graduating, he completed a 2-year post doctoral fellowship in Biological Psychiatry and Neuroscience. Dr. Light is an Assistant Professor in the UCSD Department of Psychiatry, the Associate Director of the UCSD Schizophrenia Research Program, as well as the Associate Director of the Clinical Neuroscience Unit of the VISN-22 Mental Illness Research, Education, and Clinical Center (MIRECC). Dr. Light is the UCSD Site Coordinator of the Consortium on the Genetics of Schizophrenia (COGS), a 7-university collaborative research program funded by the National Institutes of Health designed to identify the genetic basis of neurophysiologic and cognitive abnormalities of schizophrenia.

Research Interests

Research Focus

Dr. Light’s research focuses on the neurophysiologic, endophenotypic, cognitive, and functional abnormalities of schizophrenia patients. Dr. Light’s research is funded by the National Institutes of Health and the National Alliance for Research on Schizophrenia and Depression (NARSAD) to study the relationship of measures of preattentive sensory information processing with higher-order cognitive and functional outcomes in schizophrenia patients.

Clinical Focus

Dr. Light’s clinical work includes the assessment of psychiatric symptoms in individuals with schizophrenia and their family members as part of the Consortium on the Genetics of Schizophrenia. He supervises graduate students in Cognitive Science, Experimental Psychology, Clinical Psychology, and Pharmaceutical Science as well as neuropsychology interns, and post-doctoral scientists in psychiatry. Dr. Light is also a regular instructor for the medical students on their psychiatry clerkship.
