A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only publications and corresponding citation data within the specific discipline of Materials Science. This focused approach ensures that the ranking accurately reflects domain-specific research impact rather than overall scholarly output.
Scope of Research and Qualification Criteria
The ranking process began with the examination of 279,971 scientist profiles identified from a wide array of bibliometric sources covering all scientific disciplines. Within this dataset, 45 scientists were specifically identified under the Materials Science discipline.
To qualify for inclusion in the Materials Science ranking, a researcher was required to have a D-index of at least 40, alongside a majority of their tier publications concentrated within Materials Science. Furthermore, recognition of awards and achievements pertinent to the discipline was also factored into the evaluation to holistically assess each scientist’s contribution.
The D-index thresholds for recognizing top researchers are strategically set as increments of 10, relative to the total estimated number of scholars in each discipline. This method ensures that the top 1% of leading scholars are systematically incorporated in the list. Additionally, it was mandated that the proximity between a scientist’s general H-index and their D-index not exceed 30%, guaranteeing that their research specialization aligns closely with their broader citation impact.
Additional Verification Practices
The researchers managing this ranking are acutely conscious that raw bibliometric data cannot serve as an absolute measure of scholarly output or quality. Consequently, all scientist profiles underwent meticulous manual verification and were cross-correlated against publications found in a wide array of trusted scientific journals and conference proceedings.
While the number of papers published in prominent venues does not directly influence a researcher’s position in the ranking, it is considered a valuable secondary indicator of a scientist’s influence and contribution within their field.
The final ranking positions are established based on each researcher’s D-index derived from data obtained through OpenAlex and CrossRef, the foremost bibliometric databases currently accessible to the global research community.
