John Daniel Ragland, Ph.D.
- Professor, Department of Psychiatry and Behavioral Sciences
Philosophy of Care
I utilize an evidence-based cognitive behavioral therapy approach.
Dr. Ragland is a clinical psychologist, with specialty training in neuropsychology, cognitive neuroscience, and functional neuroimaging. His clinical work is primarily with early psychosis patients, and he offers standardized intake assessment interviews and supervision of cognitive behavioral therapy based individual and group interventions.
Dr. Ragland is a Professor of Psychiatry and Behavioral Sciences at the University of California at Davis. He uses behavioral, functional neuroimaging, and electrophysiology methods to identify brain networks responsible for specific aspects of learning and memory, and to test the impact of psychotic disorders on these brain systems and memory functions, with the goal of identifying relative strengths and weakness to guide development of cognitive enhancing interventions.
Dr. Ragland serves on the editorial boards of Biological Psychiatry, Psychiatry Research: Neuroimaging, Schizophrenia Research and Treatment, Faculty of 1000 Medicine, is a recipient of the EJLB Young Investigator Award and Hoffman Trust NARSAD (now Brain & Behavior Research Foundation) Independent Investigator Award, a Robert Wood Johnson Foundation grant, and has received continuous funding through the NIMH.
