Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Materials Science Scientists in Brunei Darussalam Ranking is primarily founded on comprehensive bibliometric data sourced from OpenAlex and CrossRef, supplemented by multiple other reputable data sources. These platforms constitute some of the most prominent, authoritative, and widely recognized bibliometric databases available to the global research community. The citation-based metrics utilized in constructing this ranking were meticulously collected on January 12, 2026, ensuring the most up-to-date and accurate representation of scholarly output and impact.
The ranking methodology centers on the use of the D-index (Discipline H-index), a refined metric that considers only the publications and citation data pertaining specifically to the examined scientific discipline—in this case, Materials Science. This tailored approach ensures that each scientist's ranking position reflects their specialized influence and contribution within their core field of research.
Scope of Research and Selection Criteria
The ranking comprehensively reviewed 279,971 scientist profiles aggregated from diverse bibliometric data repositories encompassing a broad spectrum of disciplines. Within this extensive dataset, 1 scientist specializing in Materials Science from Brunei Darussalam was identified and evaluated.
To qualify for inclusion in the ranking, a scientist must demonstrate a D-index of at least 40. Moreover, the majority of their tier publications are required to be situated within the domain of Materials Science, underscoring a clear research focus. Additional considerations include documented awards and notable achievements relevant to the field, reinforcing the scholar’s standing and contributions.
The threshold for the D-index is not static but calibrated in increments of 10 relative to the estimated total number of scholars active within each discipline. This calibrated threshold effectively ensures that the ranking includes the top 1% of leading scholars, maintaining the highest standard of excellence. Furthermore, eligibility incorporates a criterion requiring that there be a proximity of 30% or less between a scientist’s general H-index and their D-index, ensuring discipline-specific relevance without significant disparity between overall and specialized impact.
Verification and Validation Practices
Understanding that raw bibliometric indicators alone are insufficient to fully capture a researcher's scholarly impact, the team behind this ranking undertook rigorous manual verification of all scientist profiles. These profiles were cross-correlated against publications catalogued in a wide array of trustworthy and independent sources, reinforcing the accuracy and credibility of the data presented.
Although the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is regarded as a valuable secondary signal reflecting their ongoing scientific contributions within a specific domain.
The final ranking positions are determined using each researcher's D-index derived from data extensively gathered from OpenAlex and CrossRef. We encourage readers and stakeholders interested in a detailed understanding of our comprehensive methodology to visit our methodology page.
