A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only publications and citations pertinent to the specific discipline of Materials Science. This focused approach enables a more accurate assessment of a researcher’s impact within their field, filtering out contributions unrelated to the discipline examined.
Scope of Research and Eligibility Criteria
The ranking examines a total of 279,971 scientist profiles identified across diverse bibliometric sources, spanning all scientific disciplines. Within this extensive dataset, 12,847 scientists specializing in Materials Science were specifically evaluated.
To qualify for inclusion in the ranking, a researcher must have achieved a D-index of at least 40, ensuring that only scientists with a demonstrably significant disciplinary impact are considered. Additionally, the majority of tier publications attributed to these scientists must belong to the realm of Materials Science. Recognized awards and achievements within the field are also taken into account to further substantiate a researcher’s standing.
The threshold for the D-index is calibrated dynamically in increments of 10 depending on the estimated size of the scholar population within each discipline. This method guarantees the inclusion of the top 1% of leading scholars, ensuring representativeness without compromising selectivity. Furthermore, to maintain relevance and focus, a scientist’s general H-index and their D-index should exhibit a proximity of 30% or less, ensuring that disciplinary impact aligns closely with overall scholarly influence.
Verification Practices and Methodological Rigor
We recognize that raw bibliometric data alone can never serve as an absolute measure of a scholar’s contributions. Accordingly, every scientist profile incorporated into the ranking undergoes meticulous manual verification. Profiles are cross-correlated against publications listed in a broad array of trusted sources to confirm accuracy and authenticity.
While not directly influencing ranking positions, the volume of publications appearing in prominent journals and conference proceedings acts as a valuable secondary indicator of a scientist’s contribution to their specialized area of study. The primary ranking criterion remains the D-index, meticulously calculated from information sourced from OpenAlex and CrossRef—arguably the most prominent and reliable publicly available bibliometric databases accessible to the global research community.
