The bibliometric data underpinning the citation-based metrics were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only publications and citation counts within the specific discipline under evaluation—in this case, Materials Science. This focus on discipline-specific impact allows for a more precise and relevant assessment of scholarly contributions.
Scope of Research and Ranking Criteria
The ranking process involved the examination of 279,971 scientist profiles identified from a variety of bibliometric data sources, covering a broad spectrum of academic disciplines. Within the Materials Science discipline specifically, 1,000 scientists were identified and evaluated for inclusion in the ranking.
To qualify for the ranking, a scientist’s D-index had to be at least 40, and a majority of their tier publications had to be substantively related to the field of Materials Science. In addition to bibliometric parameters, scientists’ awards and notable achievements within Materials Science were also carefully considered as supplementary factors.
The threshold for D-index scores varies incrementally by multiples of 10 according to the total estimated number of scholars active in each discipline. This scaling is designed to ensure that the top 1% of leading scholars are consistently captured in the ranking. Furthermore, a proximity criterion was applied such that the difference between a scientist’s overall H-index and their D-index must not exceed 30%, promoting alignment between general scholarly output and discipline-specific impact.
Verification and Validation Practices
The researchers behind this ranking acknowledge that raw bibliometric data alone are insufficient for absolute evaluation of scholarly output. With this understanding, all scientist profiles were manually verified and rigorously cross-correlated against publications indexed in a wide range of trustworthy and authoritative sources. This meticulous verification process enhances the reliability and credibility of the ranking outcomes.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it serves as a valuable secondary signal of their contribution and stature in the field of Materials Science. The position in the ranking is ultimately based on each researcher’s D-index, derived from data provided by OpenAlex and CrossRef, databases recognized for their prominence and widespread adoption in bibliometric analysis.
