All bibliometric data used for calculating the citation-based metrics underpinning this ranking were collected on January 12, 2026. The ranking algorithm utilizes the D-index (Discipline H-index) as the core metric to position researchers. The D-index is a discipline-specific adaptation of the H-index that considers only publications and citations directly relevant to the examined field—in this case, Materials Science—thereby providing a focused measure of an individual researcher's impact within the discipline.
Scope of Research Considered in the Ranking
Our analysis began with a comprehensive examination of 279,971 scientist profiles drawn from various bibliometric data repositories spanning all scientific disciplines. Focusing specifically on Materials Science, 415 scientists met initial inclusion criteria for further evaluation.
To qualify for inclusion in this ranking, a scientist must have achieved a minimum D-index of 40 within Materials Science. Additionally, the majority of their tier publications—those identified as top-tier in quality and impact—had to be within the Materials Science domain. The ranking further accounts for recognized awards and notable achievements related to Materials Science to supplement citation-based metrics.
The threshold for the D-index cutoff is calibrated iteratively in increments of 10, relative to the estimated total number of scholars in each discipline. This approach ensures that the ranking reliably incorporates the top 1% of leading experts within the field. Furthermore, we maintain a proximity criterion whereby the difference between a scientist’s general H-index and their Materials Science-specific D-index does not exceed 30%, emphasizing the relevance and specialization of each researcher’s contributions.
Verification Practices and Ranking Methodology
Recognizing that raw data alone cannot capture the full scope of a researcher’s impact, the team behind this ranking employed rigorous manual verification protocols. Each scientist profile was carefully reviewed and cross-validated against publications indexed in multiple trustworthy and authoritative sources, ensuring authenticity and data integrity.
While not directly influencing a scientist’s rank, the quantity of papers published in esteemed journals and conference proceedings was monitored as a valuable secondary indicator of research activity and influence within Materials Science.
The final listing positions each scientist based on their D-index computed from data curated primarily through OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases available to the research community.
