A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined metric that accounts solely for publications and citation counts strictly within the relevant discipline of Materials Science. This approach allows for a precise evaluation of a researcher's impact and contributions within their specific field of expertise.
Scope of Research and Eligibility Criteria
This edition of the ranking examined a broad dataset encompassing 279,971 scientist profiles identified from diverse bibliometric resources across all scientific disciplines. Within this comprehensive dataset, 817 scientists specializing in Materials Science were analyzed.
To qualify for inclusion in this ranking, researchers were required to have a minimum D-index of 40, demonstrating substantial impact within Materials Science. Additionally, a majority of their high-tier publications needed to be directly related to the field. Recognition of awards and achievements specifically in Materials Science also factored into the selection process.
The threshold for D-index qualification is dynamically calibrated in increments of 10, corresponding to the estimated total number of scholars within each discipline. This adaptive thresholding guarantees the inclusion of the top 1% of leading scholars. Furthermore, to ensure disciplinary focus and precision, the difference between a scientist’s overall H-index and their Materials Science-specific D-index is maintained to a proximity of 30% or less.
Additional Verification Practices
Recognizing that raw bibliometric data alone can never yield an absolute evaluation of scholarly output, the Research.com team undertook a rigorous process of manual verification. Every scientist profile was carefully cross-checked against publications listed in a wide array of trustworthy and authoritative sources. This manual curation aligns with our commitment to uphold the highest standards of accuracy and credibility in our rankings.
While the number of papers published in prominent journals and conference proceedings does not directly impact a researcher’s position in the ranking, such metrics serve as valuable secondary indicators of a scientist’s contribution to their domain of study.
Ultimately, rankings are established based on each researcher's D-index derived from data aggregated through OpenAlex and CrossRef, ensuring a reliable and consistent foundation for assessment.
