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

On September 19, 2025, 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 the achievements of 63 Sri Lankan scientists, including 10 researchers from the University of Colombo. The analysis presented separate datasets for career-long and recent-year impact metrics, classifying scientists into 22 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 2024, while the recent-year data specifically covered citations received during the calendar year 2024. 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 2024, Emeritus Professor Kamini Mendis, Emeritus Professor Saroj Jayasinghe, Professor Senaka Rajapakse, Professor Priyanga Ranasinghe, Professor Nadira D Karunaweera, Professor Deepika Fernando, Professor Ranil Jayawardena, Professor Dakshitha Wickramasinghe, Dr Meran Keshawa Ediriweera, and Dr Umesh Jayarajah. Additionally, Emeritus Professor Kamini Mendis, Emeritus Professor Saroj Jayasinghe, Professor Senaka Rajapakse, and Professor Nadira D Karunaweera were part of the Career-long Top Scientists list.
