A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that accounts exclusively for publications and citations within the specific discipline under examination. This targeted approach enhances the relevance and precision of the ranking by focusing on the material science contributions of each researcher.
Scope of Research and Ranking Criteria
The ranking analysis covered a total of 279,971 scientist profiles identified across a wide spectrum of bibliometric data sources, spanning all scientific disciplines. Within the domain of Materials Science, 172 scientists were specifically evaluated. To qualify for inclusion in this ranking, a scientist’s D-index had to be at least 40, ensuring that only highly influential researchers are considered. Furthermore, the majority of each candidate’s top-tier publications must be in the field of Materials Science.
In addition to bibliometric thresholds, scientists’ awards and professional achievements within Materials Science were factored into the evaluation, supporting a holistic assessment of research excellence. The threshold for D-index consideration is modular, increasing in increments of 10 depending on the overall estimated population of scholars in each discipline. This framework guarantees inclusion of the top 1% of leading researchers within the field. Moreover, a proximity constraint requires that the difference between a scientist’s general H-index and their discipline-specific D-index does not exceed 30%, supporting domain-centric rigor in ranking determination.
Additional Verification Practices
The Research.com team is fully aware that raw bibliometric data alone cannot serve as an absolute measure of scholarly output. Therefore, each scientist profile was subjected to meticulous manual verification and cross-correlation against publications indexed in a variety of reputable sources. This multi-layered vetting process enhances the credibility and accuracy of the ranking.
While the number of papers published in prestigious journals and conference proceedings is not a direct factor influencing a researcher’s ranking position, it is recognized as a valuable secondary indicator of a scientist’s impact and contribution to Materials Science. The ranking ultimately relies on the rigorously calculated D-index, derived from the extensive OpenAlex and CrossRef databases, which are among the most prominent bibliometric repositories trusted by the global research community.
