A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric that includes only the papers and citation counts within the specific discipline under examination—Materials Science in this case. This focus ensures that the ranking accurately reflects disciplinary impact rather than overall citation counts.
Scope of Research Considered
The ranking comprehensively examined 279,971 scientist profiles gathered from diverse bibliometric data sources across all disciplines. Specifically, 1,134 scientists specializing in Materials Science were identified and evaluated for this edition. To qualify for inclusion, a scientist’s D-index needed to be at least 40, with the majority of their tier publications firmly anchored within the Materials Science discipline. Additionally, the researchers’ awards and documented achievements in the field were also considered as contributing factors.
The D-index threshold is set in increments of 10 relative to the total number of scholars estimated for each discipline, allowing the inclusion of approximately the top 1% of leading scholars. Furthermore, eligibility requires that the proximity between a scientist’s general H-index and their D-index does not exceed 30%, ensuring that the ranking captures experts whose impact is primarily within Materials Science.
Additional Verification Practices
The team behind the ranking undertook rigorous manual verification to enhance the accuracy and reliability of the results. Recognizing that raw bibliometric data alone cannot fully represent the quality and influence of a researcher’s output, each scientist profile was cross-validated against publications in a wide range of trustworthy and authoritative sources.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it provides an important secondary signal of scholarly contribution and research leadership within a specific scientific domain.
The position in this ranking is established exclusively via each researcher’s D-index, based on data aggregated from OpenAlex and CrossRef. The conscientious integration of multiple data sources and manual verification underscores the meticulous approach taken to build a credible and authoritative ranking.
