Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Singapore Ranking is grounded in a rigorous and comprehensive data collection process. The primary bibliometric data sources utilized include OpenAlex and CrossRef, supplemented by multiple additional reputable datasets. Citation and publication data were meticulously gathered on January 12, 2026. To ensure precise discipline-focused evaluation, a scientist's position in the ranking is determined based on their D-index (Discipline H-index), a metric that considers only the papers and citations pertinent to the examined discipline of Materials Science.
Scope of Research and Selection Criteria
The ranking process involved the examination of 279,971 scientist profiles spanning all disciplines, with a focused subset of 195 scientists identified within Materials Science. To qualify for the ranking, scholars were required to have a D-index of at least 40, with the majority of their tier publications firmly established in Materials Science. In addition to bibliometric performance, consideration was given to the scientists' awards and notable achievements within the discipline. The threshold D-index for potential inclusion is adjusted in increments of 10 according to the estimated scholar population per discipline, ensuring inclusion of the top 1% of leading experts. Furthermore, to maintain disciplinary relevance and accuracy, a maximum proximity threshold of 30% or less between a scientist’s overall H-index and their Materials Science-specific D-index was applied.
Verification and Methodological Rigor
Understanding the inherent limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team supplemented quantitative metrics with thorough manual verification. Each scientist profile was systematically cross-checked against a wide array of trusted publication sources to confirm the accuracy and appropriateness of data attribution. Although it does not influence ranking placement, the volume of publications in prominent journals and major conference proceedings is recognized as a valuable secondary indicator of a researcher’s influence within Materials Science.
The final ranking positions are calculated strictly based on the D-index data extracted from OpenAlex and CrossRef, which are internationally acknowledged as the most comprehensive and reliable bibliometric databases available to the academic community.
