A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a discipline-specific variant of the traditional H-index. The D-index considers only those papers and corresponding citation metrics relevant to the examined discipline, thereby providing a precise measure of impact within the field of Materials Science.
Scope of Research Considered
In creating this ranking, a total of 279,971 scientist profiles were examined across all disciplines from diverse bibliometric sources. Specifically, 1,234 profiles related to Materials Science were identified and analyzed. To qualify for inclusion, a scientist’s D-index had to be at least 40, with the majority of their tier publications concentrated in the area of Materials Science. Additionally, awards and recognized achievements in Materials Science were factored into the selection process.
The threshold for the D-index is calibrated in increments of 10 based on the estimated total number of scholars within each discipline. This approach ensures that the top 1% of leading researchers are incorporated in the ranking. Furthermore, a proximity criterion is applied whereby a qualifying scientist’s general H-index and D-index must have a difference of 30% or less, reinforcing the discipline-specific relevance of the metrics.
Additional Verification Practices
Recognizing that raw bibliometric data should never serve as the sole indicator of scholarly performance, all scientist profiles included in the ranking were meticulously manually verified. Verification involved cross-correlating author profiles against publications listed in a broad range of reputable academic journals, conferences, and other trusted sources. This layer of validation enhances the reliability and credibility of the ranking outcomes.
While not directly influencing a researcher's ranking position, the quantity of publications in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of a scientist’s contributions to Materials Science. The ranking’s core metric, the D-index, is established exclusively using data sourced from OpenAlex and CrossRef—two of the most prominent and widely recognized bibliometric databases accessible to the global research community.
