Top Scientists Update Science-Wide Author Databases with Standardised Citation Indicators – Elsevier Data Repository 2025

On October 07, 2026, Elsevier released an updated dataset titled “Updated science-wide author databases of standardised citation indicators”. This comprehensive analysis was conducted by a team of experts led by Professor John P. A. Ioannidis from Stanford University, USA.
Significantly, the study recognised 82 Sri Lankan scientists, including 11 researchers from the University of Colombo. The analysis presented separate datasets for career-long and recent-year impact metrics, classifying scientists into 20 scientific fields and 174 sub-fields, as per the standard Science-Metrix classification. The career-long data were updated to include information up to the end of 2025, while the recent-year data specifically covered citations received during the calendar year 2025. The selection criteria were stringent: scientists had to either rank among the top 100,000 by c-score (with and without self-citations) or achieve a percentile rank of 2% or higher within their respective subfield.
In the list of the top scientists for the single year 2025, Emeritus Professor Kamini Mendis, Emeritus Professor Saroj Jayasinghe, Professor Nadira D Karunaweera, Professor Senaka Rajapakse, Professor Nalin de Silva, Professor Shaman Rajindrajith, Professor Ranil Jayawardena, Professor Priyanga Ranasinghe, Professor Dakshitha Wickramasinghe, Dr Meran Keshawa Ediriweera and
Dr Umesh Jayarajah.
Additionally, Emeritus Professor Kamini Mendis, Emeritus Professor Saroj Jayasinghe, Professor Nadira D Karunaweera, Professor Senaka Rajapakse and Dr Meran Keshawa Ediriweera were part of the career-long top scientists list.
While the database is a reference for standardised research impact indicators rather than an award or a global ranking, the strong representation of University of Colombo researchers highlights their dedication, research excellence, and significant scholarly contributions.
