A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citations relevant to the examined discipline—here, Materials Science. This approach ensures that the ranking reflects a researcher’s substantive impact within their field rather than their overall citation record across unrelated disciplines.
Scope of Research and Selection Criteria
The ranking was derived from an extensive examination of 279,971 scientist profiles across all scientific disciplines, curated from a diverse range of bibliometric data sources. Within Materials Science specifically, a total of 155 scientists were identified and analyzed in depth.
To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 40 and demonstrate that the majority of their top-tier publications are situated within the domain of Materials Science. Furthermore, recognition of a scientist’s awards and achievements specifically related to Materials Science was integrated into the qualification framework to acknowledge their distinguished contributions.
The threshold D-index is set dynamically in increments of 10 according to the estimated total number of scholars in each discipline, ensuring that the ranking consistently captures at least the top 1% of leading experts. Additionally, candidates must exhibit a proximity of 30% or less between their general H-index and their D-index, affirming a strong disciplinary focus and impact.
Verification and Methodological Rigor
Understanding that raw bibliometric data alone cannot fully capture the breadth and quality of scientific contributions, the researchers behind this ranking have incorporated rigorous manual verification practices. All scientist profiles were carefully cross-correlated with publications and records from a wide array of trustworthy sources to validate the integrity and relevance of their scholarly output.
Although the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it serves as an important supplementary indicator of a scientist’s active contribution and standing within the Materials Science community.
The ranking positions themselves are formally determined through each researcher’s D-index, calculated using up-to-date information sourced from OpenAlex and CrossRef—the most prominent and widely recognized bibliometric databases accessible to the research community.
