The bibliometric data underpinning the citation-based metrics utilized in this ranking were collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that considers only papers and citation metrics within the examined discipline—in this case, Materials Science—thus reflecting specialized impact and productivity in the domain.
Scope of Research and Qualification Criteria
The framework for this ranking involved examining 279,971 scientist profiles compiled from a variety of authoritative bibliometric data sources across all disciplines. Within Materials Science specifically, 196 scientists were reviewed for potential inclusion.
To qualify for the ranking, a scientist’s D-index must meet or exceed a threshold of 40. Additionally, a majority of their tier publications needed to be squarely within the Materials Science domain. Beyond bibliometric performance, scientists’ awards and notable achievements in the field were also incorporated as qualitative factors.
The D-index threshold is dynamically set in increments of 10, calibrated against the total estimated number of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading scholars. Furthermore, to maintain disciplinary relevance, there is a requirement that the proximity between a scientist’s overall H-index and their discipline-specific D-index does not exceed 30%.
Verification and Methodological Rigor
The Research.com team recognizes that raw bibliometric data alone cannot provide an absolute measure for evaluating scholarly output. Consequently, all scientist profiles were manually verified and cross-correlated against publications indexed in a wide array of trustworthy and peer-recognized sources. This meticulous validation process guarantees the reliability and accuracy of the ranking.
While not directly influencing the position in the ranking, the number of publications in prominent journals and conference proceedings is also considered a valuable secondary signal of a scientist’s contributions within Materials Science.
Ultimately, the researcher’s D-index, computed from OpenAlex and CrossRef data — two of the most prominent bibliometric databases available — forms the cornerstone of the ranking methodology.
