All bibliometric data underpinning the citation-based metrics employed in this ranking were collected on January 12, 2026. A key metric driving the ranking is the D-index (Discipline H-index), which specifically measures a researcher’s scientific output and citation impact restricted to the discipline under evaluation—in this case, Materials Science. This focused approach ensures that only papers and citation metrics relevant to Materials Science contribute to a scientist’s position in the ranking.
Scope of Research and Selection Criteria
The ranking process began with an extensive examination of 279,971 scientist profiles compiled from a broad array of bibliometric data sources spanning all academic disciplines. Within this vast dataset, 2,421 scientist profiles were identified as contributors within the field of Materials Science.
To qualify for inclusion in the ranking, each scientist was required to have a D-index of at least 40, reflecting a substantial scientific contribution specifically within Materials Science. Moreover, a majority of their tier publications had to be categorized clearly within this discipline. Alongside quantitative metrics, awards and other significant professional achievements in Materials Science were factored into the evaluation to capture broader scholarly contributions.
The D-index threshold for top researchers is dynamically set in increments of 10, calibrated according to the estimated total number of scholars within each discipline. This methodology guarantees that the ranking reliably includes the top 1% of leading experts. Additionally, to ensure disciplinary focus, a scientist’s general H-index and their Materials Science-specific D-index were required to remain within a proximity of 30% or less.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly impact, the Research.com team implemented rigorous additional verification procedures. Each scientist profile was manually reviewed and cross-correlated with publications indexed in a wide array of trustworthy academic sources. This thorough vetting process enhances the credibility and accuracy of the ranking.
Although not a direct factor in determining a scientist’s position within the ranking, the quantity of publications appearing in prestigious journals and leading conference proceedings was considered a valuable secondary indicator of substantive contributions to Materials Science research.
The final ranking positions are established using each researcher’s D-index as derived exclusively from data gathered via OpenAlex and CrossRef—currently the most prominent and widely trusted bibliometric databases accessible to the global research community.
