Cal State Fullerton has once again been recognized for its research excellence, with 24 faculty members ranked among the top 2% of the most-cited researchers worldwide, a distinction that reflects the university’s scholarly impact on a global scale.
The list appears in the “Updated Science-Wide Author Databases of Standardized Citation Indicators,” compiled by Elsevier, a globally recognized leader in scientific publishing and analytics. It highlights researchers whose work is frequently cited by peers, a key indicator of scholarly impact.
“Being recognized among the most-cited scholars reflects the significant impact our faculty have in advancing knowledge across their fields,” said Binod Tiwari, associate vice president for research and sponsored programs.
“Their work not only contributes to academic progress and enhances the university’s reputation, but it also enriches the learning experience for our students by bringing relevant scholarship into the classroom.”
The database includes those who rank among the top 100,000 researchers worldwide or fall within the top 2% of their field. Scientists are grouped into 22 broad scientific fields and 174 subfields. Rankings are based on how often a researcher’s work is cited by others, with and without self-citations.
This year, 10 CSUF faculty members were recognized for both their career-long and 2025 single-year citation impact. An additional 14 faculty were included based on either their lifetime citation record or their citation performance during 2025.
The list features current, retired, emeritus and deceased faculty whose work spans a wide range of disciplines including psychology, physics, biology, chemistry, engineering, kinesiology, communication studies, English, social work, management and finance.
Cal State Fullerton ranks fifth among all California State University campuses for the number of faculty recognized, reflecting the institution’s research footprint and commitment to academic excellence.
