Congratulations to the University of Sri Jayewardenepura Researchers!
On September 19, 2025, Elsevier released its updated dataset titled “Updated science-wide author databases of standardised citation indicators” in the Elsevier Data Repository. This comprehensive analysis, led by Professor John P.A. Ioannidis of Stanford University, USA, evaluates the global scientific impact of researchers across disciplines.
The study recognised the achievements of 63 Sri Lankan scientists, including seven distinguished researchers from the University of Sri Jayewardenepura. The analysis considered both career-long and recent-year citation impact, covering 22 scientific fields and 174 sub-fields according to the Science-Metrix classification. Scientists were selected based on rigorous criteria: inclusion among the top 100,000 by c-score (with/without self-citations) or ranking in the top 2% of their respective subfield.
Seven USJ researchers named to the World’s Top 2% Scientists list (based on Scopus data):
- Vithanage, Meththika Suharshini – Rank: 8,301
- Rajapaksha, Anushka Upamali – Rank: 58,635
- Gunaratne, Nuwan – Rank: 84,340

- Ekanayaka, Anusha Hasini – Rank: 457,802
Five of these researchers are from the Faculty of Applied Sciences, one from the Faculty of Technology, and one from the Faculty of Management Studies and Commerce.
“Including seven USJ researchers in the prestigious top 2% scientists list is a proud moment for the university and Sri Lanka. It recognises the excellence of our research and the dedication of our scholars. I thank them all for contributing to our university’s global research ranking.” said Senior Prof. Pathmalal M. Manage, Vice Chancellor of University of Sri Jayewardenepura.
