Dr. Light also serves as the Director of Mental Health Research and the Administrative Director of the Mental Illness, Research, Education and Clinical Center (MIRECC) at the VA San Diego Healthcare System. Dr. Light’s research has advanced the use of objective, laboratory-based biomarkers for predicting and tracking therapeutic response to cognitive and pharmacologic interventions in schizophrenia patients.

Research Interests

Research Focus

Dr. Light has been a contributor and leader of the UCSD Schizophrenia Program. He has overseen the recruitment, clinical evaluation, and biomarker testing of thousands of participants, including schizophrenia patients, their family members, and nonpsychiatric subjects. Dr. Light provides clinical and laboratory-based training for UCSD and national research programs as part of the Consortium on the Genetics of Schizophrenia.

Clinical Focus

Dr. Light received his Ph.D. from the top-ranked SDSU-UCSD Joint Doctoral Program in Clinical Psychology with an emphasis in Neuropsychology and Neurophysiology in 2001. Following graduate school, he completed a 2-year Fellowship in Biological Psychiatry and Neuroscience at UCSD. He has published over 100 articles that have appeared in the top journals of psychiatric neuroscience. Dr. Light’s work has been prominently featured in policy reports from the Institute of Medicine for next-generation strategies for personalized treatments of psychotic disorders.
