    Biography

    Dr. Perry received his Ph.D. from the California School of Professional Psychology, San Diego in 1989. He completed his Internship and post-doctoral Fellowship at UCSD. He is a Fellow of the National Academy of Neuropsychology (NAN) as well as the Society for Personality Assessment and he serves as the Executive Director of NAN. His primary position in the Department of Psychiatry is as Vice Chair for Program Development and Operations and as the
    Co-Director, Division of Clinical Psychiatry. He also serves as the Chief Supervising psychologist at UCSD-Medical Center and engages in neuropsychological assessments.

    Research Interests

    Dr. Perry’s primary research program focuses on inhibitory and information processing deficits in neuropsychiatric conditions. He is the recipient of several grants to study acutely, un-medicated psychiatric patients using psychophysiological measures in order to characterize their inhibitory functions. Additionally, he is interested in conducting longitudinal studies, relating information processing deficits to thought disorder, neuropsychological and clinical measures. Although a majority of his publications are on patients with bipolar illness and schizophrenia, he has funded grants to study people with substance use disorders as well as people with viral diseases such as HIV and Hepatitis C.

    Clinical Focus

    As an active clinical Director, Dr. Perry serves as an Attending and is engaged in Psychiatry Consultation-Liaison work. He oversees consultation programs that have been developed with the UCSD Anesthesia Pain Management Group, Transplantation services and the Burn Service. He also serves as the Chief Supervising Psychologist at UCSD-Medical Center and as a member of Neuropsychological Associates is involved in outpatient neuropsychological and psychodiagnostic assessment.
