PROVENANCE AND METHODS

How to read these data

These tables are a Thai University Rankings summary of John P.A. Ioannidis’s scientist database published in the Elsevier Data Repository.

Version and period
V9, published 7 Oct 2026, uses the 1 Aug 2026 Scopus snapshot and citation data through 2025. Citation year and release year differ.
Population counted
Filtered to cntry = tha, the source’s country for the most recent affiliation. Includes all nationalities, with no nationality inferred from names. This is not a count of all scientists in Thailand.
Database inclusion
The source selects the top 100,000 by c-score, with and without self-citations, or the top 2% within a subfield. The common Top 2% label should be read with these inclusion criteria.
Affiliation consolidation
Faculties and campuses with an explicit parent university are consolidated. Siriraj and Ramathibodi are included under Mahidol, while original affiliations remain visible. The joint Mahidol–Oxford research unit is kept separate. Ambiguous affiliations are retained and flagged.
Fields used
Uses each record’s sm-field and sm-subfield-1. One main field and one primary subfield are counted per record, preventing field totals from being duplicated.
Interpretation
Counts describe included scientists’ citation impact. These are not institutional rankings produced by Stanford, do not measure teaching or overall quality, and may reflect institution size. Absence from the list does not mean poor research.
