Bibliometric data used to derive citation-based metrics were collected on January 12, 2026. Each scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only publications and citation data specific to the Materials Science discipline. This approach enables precise and relevant assessment of scholarly impact within the targeted research field.
Scope of Research and Qualification Criteria
The ranking evaluates an extensive pool of 279,971 scientist profiles compiled from multiple bibliometric sources, spanning all scientific disciplines. Within this dataset, 222 scientists specializing in Materials Science were identified and analyzed in detail.
To qualify for inclusion in this ranking, a scientist’s D-index in Materials Science must be at least 40. Additionally, a majority of their tier publications need to be clearly categorized within the Materials Science domain. The evaluation also takes into account each scientist's awards and significant achievements pertinent to the field, emphasizing excellence beyond citation metrics.
The D-index threshold is dynamically calibrated in increments of 10 relative to the estimated total number of scholars in each discipline, with the intention of ensuring that the top 1% of leading experts are consistently represented. Furthermore, candidates exhibit a close alignment between their general H-index and D-index, typically with a proximity of 30% or less, underscoring the disciplinary focus of their scholarly contributions.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully capture the quality and impact of scholarly work, the Research.com team employs rigorous manual verification procedures. Each scientist profile included in the ranking has been carefully reviewed and cross-validated against publications indexed in a wide array of trustworthy sources, to ensure accuracy and integrity of the data.
While the number of papers published in respected journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of a scientist’s contributions to their field.
The ranking position itself is established strictly based on each researcher’s D-index, derived from data aggregated from OpenAlex, CrossRef, and affiliated databases. These platforms represent the most authoritative and comprehensive sources available for such bibliometric evaluations.
