A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only publications and citation counts within the specific discipline under analysis. This approach ensures that the ranking reflects specialized expertise and impact in Materials Science rather than general research output.
Scope of Research and Inclusion Criteria
The ranking process examined 279,971 scientist profiles drawn from an extensive range of bibliometric datasets encompassing all scientific disciplines. Within Materials Science specifically, 10 scientists were identified and evaluated. To qualify for inclusion, a scientist was required to have a minimum D-index of 40, with a majority of their tier publications falling squarely within the domain of Materials Science.
Additional qualitative factors, such as documented awards and notable achievements in Materials Science, were also considered to reinforce the robustness of the evaluation. The threshold for the D-index is calibrated in increments of 10 based on the total estimated number of scholars in each discipline, guaranteeing that the top 1% of leading researchers are incorporated into the list. Moreover, a proximity criterion mandates that the difference between a scientist’s general H-index and their D-index should be 30% or less, ensuring a strong disciplinary focus.
Verification and Robustness Practices
We recognize that raw bibliometric data alone can never serve as an absolute measure of a researcher’s scientific contributions. Accordingly, every scientist profile included in this ranking underwent meticulous manual verification. This process involved cross-referencing publications across a broad array of credible academic sources to confirm accuracy and completeness.
While the number of publications in prominent journals and conference proceedings does not directly influence the ranking positions, it constitutes a valuable secondary indicator of a scientist’s research contributions within Materials Science. The ranking positions themselves are established strictly using each researcher’s D-index, calculated from data aggregated by OpenAlex and CrossRef — the foremost and most reliable bibliometric databases available to the global research community.
