The bibliometric data used to devise the citation-based metrics integral to this ranking were collected on January 12, 2026. This timing ensures the inclusion of the most up-to-date and relevant scholarly output available at the time of analysis.
A researcher’s position in the ranking is determined exclusively by their D-index (Discipline H-index), a refined metric that considers only those papers and citation counts within the specific discipline under examination—in this case, Materials Science—offering a precise and discipline-focused measure of research impact.
Scope of Research and Ranking Criteria
The scope of the ranking encompasses a thorough examination of 279,971 scientist profiles identified through a variety of bibliometric data sources, spanning all academic disciplines. Within this broad dataset, 44 scientists specializing specifically in Materials Science were evaluated.
To qualify for inclusion in this ranking, a scientist must have achieved a minimum D-index of 40. Additionally, a majority of their tier publications must fall within the Materials Science discipline to ensure relevance and specialization. Consideration was also given to notable awards and achievements attained by the scientists within the field.
The threshold for D-index selection is incrementally adjusted by 10 depending on the estimated total number of scholars in each discipline, thereby maintaining the rigor of the ranking while ensuring inclusion of the top 1% of leading experts. Moreover, to demonstrate disciplinary focus and consistency, there must be no greater than a 30% difference between a scientist’s overall H-index and their discipline-specific D-index.
Additional Verification Practices
The researchers behind this ranking recognize that raw bibliometric data alone cannot serve as an absolute evaluative tool for scholarly output. Consequently, all scientist profiles included in the ranking underwent meticulous manual verification. This process involved cross-correlating publication records across a suite of trustworthy and independent sources to confirm accuracy and relevance.
Although the number of papers published in prominent journals and conference proceedings is not a direct factor influencing a researcher’s position in the Research.com ranking, it is regarded as a valuable secondary indicator of scientific contribution and productivity within a given field.
The final position of each scientist is established based on their D-index, derived strictly from information gathered through OpenAlex and CrossRef—two of the most prominent and recognized bibliometric databases accessible to the global research community.
