A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that accounts exclusively for publications and citations within the specific discipline of Materials Science. This approach guarantees an accurate reflection of each researcher’s influence in their core area of expertise, rather than their overall scholarly output.
Scope and Criteria of the Ranking
The compilation of this ranking involved analysis of 279,971 scientist profiles drawn from a variety of bibliometric data sources spanning all scientific disciplines. For Materials Science specifically, 30 scientist profiles were evaluated.
To qualify for inclusion in the ranking, a researcher’s D-index needed to be at least 40. Additionally, a majority of their tier publications had to be in the area of Materials Science, ensuring subject matter relevance. Awards and notable achievements within the Materials Science domain were also considered qualitatively to supplement the bibliometric measures.
The threshold for the D-index is adjusted in increments of 10 relative to the estimated total population of scholars in each discipline, a strategy designed to incorporate the top 1% of leading experts. Furthermore, inclusion required that the difference between a scientist's general H-index and their D-index remain within 30% to confirm discipline-focused impact.
Verification and Methodological Rigor
Understanding that raw bibliometric data cannot serve as an absolute measure of a scholar’s contributions, the Research.com team meticulously conducted manual verification of all scientist profiles. Each profile was cross-checked with publications indexed in an extensive range of trusted academic sources to ensure accuracy and authenticity.
While not directly influencing the ranking position, the number of papers published in prominent journals and conference proceedings was also noted as a valuable secondary indicator of research contribution within Materials Science.
The ranking positions themselves are established using the D-index, calculated from data gathered primarily through OpenAlex and CrossRef — two of the most comprehensive and widely acknowledged bibliometric databases accessible to the research community.
