Institutional Overview

Historical Development and Growth

UCI was founded in 1965 as part of the University of California system’s expansion to serve the growing population of Southern California. From its earliest days, the university emphasized interdisciplinary research and innovation, establishing strong programs in the biological sciences that would later become the foundation for its neurodegenerative disease research.

The modern era of neuroscience research at UCI began in the 1980s and 1990s, with the establishment of the Institute for Memory Impairments and Neurological Disorders (UCI MIND) and related research centers. These investments positioned UCI as a leading center for Alzheimer’s disease research, with particular strengths in biomarker development, clinical trials, and basic science investigations of disease mechanisms.

The university has continued to expand its neuroscience research infrastructure, establishing the Center for Neural Circuit Mapping, the Institute for Immunology, and the Sue & Bill Gross Stem Cell Research Center.
