The bibliometric data used to devise the citation-based metrics for this ranking were collected on January 12, 2026, ensuring that the evaluation is based on the most current and relevant information available. A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively considers papers and citation metrics strictly within the examined discipline. This focus allows for a more accurate assessment of a researcher’s impact and contribution specifically to Materials Science.
Scope of Research and Qualification Criteria
The ranking is founded on an extensive examination of 279,971 scientist profiles drawn from a broad array of bibliometric data sources, spanning all academic disciplines. Within this dataset, 2,000 scientists were identified specifically from the field of Materials Science for detailed inclusion.
To qualify for the ranking, a scientist’s D-index in Materials Science had to be at least 40, reflecting a significant and sustained contribution to the discipline. Additionally, the majority of the candidate’s tier publications had to be concentrated in Materials Science, ensuring domain relevance. Recognition of awards and notable achievements within the field also factored into the candidate selection process.
The threshold for the D-index is dynamically set as increments of 10, calibrated against the total estimated number of scholars in each discipline. This method guarantees that the top 1% of leading scholars in Materials Science, based on discipline-specific research impact, are incorporated. Furthermore, to ensure consistency and domain focus, a proximity criterion was applied requiring a difference of 30% or less between a scientist’s general H-index and their Materials Science D-index.
Additional Verification Practices
At Research.com, we recognize that raw bibliometric data alone can never serve as an absolute tool to evaluate scholarly output. Accordingly, all scientist profiles included in the ranking were subjected to manual verification and cross-correlation against publications listed in a wide range of trustworthy and authoritative sources. This rigorous scrutiny ensures the integrity and accuracy of the ranking.
While not directly impacting a researcher’s position in the ranking, the volume of papers published in prominent journals and conference proceedings is considered a valuable secondary signal of a scientist’s contribution to their specific research area, further supporting the holistic assessment of impact.
Position determination in the ranking is firmly based on each researcher’s D-index, as calculated from data aggregated through OpenAlex and CrossRef. These databases provide unparalleled coverage and reliability, reflecting the research community’s broad consensus on bibliometric sources.
