A scientist’s position in this ranking is governed by their D-index (Discipline H-index), a refined bibliometric measure that applies citation metrics exclusively to publications and impact within the specified discipline—in this case, Materials Science. Unlike the general H-index, the D-index focuses on discipline-specific scholarly output and citations, enabling a more precise assessment of a researcher’s influence within their specialized area of study.
Scope of Research and Criteria
For the construction of this ranking, a total of 279,971 scientist profiles derived from multiple bibliometric sources across all disciplines were initially examined, out of which 12,851 scientists were identified specifically within the field of Materials Science.
To qualify for inclusion in the ranking, a scientist was required to meet several stringent criteria:
- Their D-index had to be at least 40, ensuring that only researchers with substantial and sustained impact in the discipline were considered.
- A majority of their tier publications—those with significant citation impact—had to be identified as belonging to the Materials Science domain.
- Awards and notable achievements within Materials Science were also factored into the selection process to complement the quantitative data.
The threshold for the D-index is dynamically calibrated in increments of 10, based on the estimated population size of researchers within each discipline. This approach guarantees that the ranking incorporates the top 1% of leading scholars in Materials Science, maintaining both exclusivity and representativeness among the highest-impact scientists. Additionally, the methodology ensures there is a proximity of no more than 30% between a scientist’s general H-index and their D-index to affirm that their disciplinary impact closely reflects their overall research influence.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone can never provide a definitive evaluation of academic contributions, the Research.com team has implemented a thorough manual verification process for all scientist profiles included in the ranking. This manual curation involves cross-referencing researcher publication records against a diverse array of reputable sources and databases to confirm accuracy and relevance.
While the number of papers published in high-impact journals and leading conference proceedings does not directly influence a researcher’s ranking position, it nevertheless provides a valuable secondary signal of their prominence and contribution within the Materials Science community.
The ranking positions are primarily established through the D-index calculated from data obtained via OpenAlex and CrossRef, given their recognition as the most reliable and comprehensive bibliometric repositories available to researchers worldwide.
