All citation-based metrics employed in the ranking were derived from bibliometric data collected on January 12, 2026. A scientist’s position in the ranking is determined by their Discipline H-index (D-index), a metric focused exclusively on publications and citations within the specific discipline of Materials Science. This approach provides a more precise assessment of a researcher’s contributions to their field rather than a generalized measure across all research areas.
Scope of Research and Qualification Criteria
The ranking encompasses an analysis of 279,971 scientist profiles identified from a broad range of bibliometric sources across all disciplines. For Materials Science specifically, the dataset included 590 scientists whose research focuses on this field.
To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 40. In addition, a majority of their tier publications had to be centered specifically in Materials Science, ensuring relevance and specialization. Awards and notable achievements within the Materials Science discipline were also taken into account to strengthen the validity of the ranking.
The D-index threshold for considering top researchers is adjusted in increments of 10 depending on the estimated total number of scholars per discipline. This adaptive threshold guarantees that the top 1% of leading scholars are represented on the list, reflecting the highest caliber of research excellence. Furthermore, to maintain discipline-specific relevance, the D-index must not deviate from the researcher’s general H-index by more than 30%, ensuring alignment between overall and disciplinary impact.
Quality Assurance and Verification Practices
The Research.com team recognizes that raw bibliometric data alone is insufficient as an absolute measure for evaluating individual scholars. With this in mind, every scientist profile included in the ranking was manually verified and cross-correlated against publications indexed in a variety of trustworthy sources to safeguard accuracy and reduce errors.
While not influencing the ranking position directly, the volume of papers published in prominent journals and major conference proceedings associated with Materials Science is considered an important secondary indicator of research contribution and influence within the discipline.
The ranking positions themselves are established strictly based on each scientist’s D-index, utilizing data compiled from OpenAlex and CrossRef—two of the most respected and widely used bibliometric databases available to the global research community.
