Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Brunei Ranking is primarily based on bibliometric data aggregated from OpenAlex and CrossRef, complemented by multiple other reputable data sources. The comprehensive citation-based metrics utilized to formulate this ranking were collected on January 12, 2026. The ranking methodology centers on a researcher's D-index (Discipline H-index), which is calculated exclusively from papers and citations relevant to the specific discipline under examination—in this case, Materials Science. This focused approach ensures that the ranking reflects a scientist’s scholarly influence within their specialized research domain rather than their overall citation footprint.
Scope of Research and Qualification Criteria
The ranking evaluated a total of 279,971 scientist profiles gathered across a broad spectrum of bibliometric databases spanning all disciplines worldwide. Specifically, for the Materials Science discipline, the study examined 1 scientist profile from Brunei. To qualify for inclusion in the ranking, a scientist must satisfy several stringent criteria:
- Their D-index must be at least 40.
- The majority of their tier publications must have been published within the field of Materials Science.
- Acknowledged awards and demonstrable academic achievements in Materials Science are also considered.
The D-index threshold of 40 reflects an incremental scale set in steps of 10, which is determined based on the estimated total number of scholars in each discipline. This ensures that the ranking consistently incorporates the top 1% of leading researchers per discipline. Additionally, to establish discipline specialization, there must be a proximity of 30% or less between the scientist’s general H-index and their D-index, which validates a concentrated research output in the field of Materials Science.
Verification and Methodological Rigor
The research team behind this ranking fully recognizes that raw bibliometric data alone cannot serve as an absolute measure of academic output or impact. Consequently, each scientist profile has undergone manual verification and cross-correlation against an extensive array of trustworthy publication sources. While a researcher’s position in the ranking is determined solely by their D-index, the number of publications in leading journals and prominent conference proceedings is considered an important supplementary indicator of their contribution to the advancement of Materials Science research.
This ranking’s positions are assigned using data derived from OpenAlex and CrossRef, which are globally acknowledged as two of the most prominent and reliable bibliometric databases available to the scientific community.
