A scientist’s position within this ranking is determined by their Discipline H-index, or D-index. This metric focuses exclusively on the number of published papers and citation counts within the specific discipline under examination — in this case, Materials Science — providing a more accurate reflection of their impact within the field.
Scope of Research and Qualification Criteria
The ranking rigorously examined a total of 279,971 scientist profiles aggregated from a variety of bibliometric data sources across all disciplines, narrowing the focus to 532 scientists engaged specifically in Materials Science. To qualify for inclusion in this prestigious list, a scientist must have achieved a minimum D-index of 40 within Materials Science, with a majority of their tier publications concentrated in this area.
In addition to bibliometric thresholds, the evaluation process also considered the scientists’ documented awards and notable achievements within the field, recognizing their broader contributions beyond citation metrics. The threshold for D-index consideration is adjusted in increments of 10 relative to the estimated total number of scholars in each discipline, guaranteeing that the top 1% of leading researchers are incorporated within the ranking. Furthermore, to ensure disciplinary focus, a candidate’s D-index must be within 30% or less of their general H-index, thereby confirming a strong alignment between their overall impact and their specialized contributions to Materials Science.
Verification and Methodological Rigor
In acknowledgment of the limitations inherent in raw bibliometric data as an absolute measurement of scholarly output, all scientist profiles included in this ranking were subjected to meticulous manual verification. This involved cross-referencing publication records with a broad range of trusted sources to confirm accuracy and relevance.
While not influencing ranking position, the quantity of publications in prominent journals and leading conference proceedings serves as an important secondary indicator of a scientist’s contribution to the Materials Science community. The core ranking positions are established strictly using each researcher’s D-index derived from OpenAlex and CrossRef, the most comprehensive and widely recognized bibliometric databases available to the research community today.
