An institution's position in the ranking is determined by the cumulative D-indexes (Discipline H-index) of all affiliated scholars whose predominant publication area is Materials Science. The D-index is a focused metric that exclusively considers publications and citations within a given discipline, ensuring discipline-specific influence is accurately assessed.
Scope of Research and Inclusion Criteria
To build a representative and robust evaluation, 279,971 scientist profiles sourced from an extensive pool of bibliometric data were meticulously examined. Of that, 37,821 scientists engaged specifically in Materials Science were analyzed for this ranking.
- The qualifying threshold for inclusion was set at a D-index of 40. Only scientists with the majority of their publications in the Materials Science discipline were considered.
- The D-index threshold for top researchers is incrementally increased by 10, depending on the estimated number of scholars within each discipline. This method guarantees the top 1% of leading scholars are included.
- A proximity criterion ensured that the difference between a scientist's general H-index and their D-index did not exceed 30%, thus assuring domain relevance.
- Scientists’ awards and achievements in Materials Science were also incorporated as secondary validation factors.
Verification and Quality Assurance Practices
We recognize that raw bibliometric data is not absolute and should not be treated as the sole indicator of scientific merit. Accordingly, all scientist profiles underwent robust manual verification, with cross-correlation against publications in a broad range of reputable sources.
While not used in determining rank position, the number of articles published in high-impact journals and international conference proceedings is acknowledged as a valuable signifier of a scientist’s contribution to the discipline.
Ranking positions are assigned using each researcher’s H-index data sourced from OpenAlex and CrossRef, which are established as leading bibliometric data platforms in the academic world. To learn more about the full framework, visit our methodology page.
