A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric metric that considers only papers and citation metrics specifically within the examined discipline of Materials Science. This discipline-focused approach ensures that the ranking reflects the impact and relevance of each researcher’s contributions solely within the Materials Science domain.
Scope and Selection Criteria
The ranking was constructed after examining 279,971 scientist profiles identified from a diverse array of bibliometric databases spanning all scientific disciplines. Specifically, for the Materials Science discipline, a subset of 1,000 scientists was analyzed. Qualification for inclusion in the ranking required scientists to have a minimum D-index of 40, with the majority of their tier publications concentrated in the area of Materials Science. Additionally, a scientist’s awards and notable achievements within the field were taken into account to further contextualize their standing.
The D-index threshold for inclusion is dynamically adjusted in increments of 10, relative to the estimated total number of scholars within each discipline. This approach simultaneously maintains a rigorous standard while ensuring that the top 1% of leading experts are comprehensively incorporated into the list. Furthermore, to maintain the relevance of the discipline-specific metric, only candidates whose general H-index and D-index have a proximity difference of 30% or less were considered.
Verification and Validation Practices
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s output or impact. To ensure the highest level of accuracy and reliability, every scientist profile has undergone manual verification, including cross-correlation against a wide range of trustworthy publication sources and authoritative records.
While not directly influencing the ranking positions, the volume of a researcher’s publications in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of scholarly contribution in Materials Science.
The final ranking is established by applying each researcher’s D-index, derived from bibliometric information gathered chiefly via OpenAlex and CrossRef, which are among the most prominent and well-regarded citation databases accessible to the global research community.
