The bibliometric data underpinning the citation-based metrics for this ranking were collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a metric that considers only the publications and citation impact within the specific discipline under examination—in this case, Materials Science. This approach allows for a more precise assessment of scholarly influence within the relevant field.
Scope of Research and Inclusion Criteria
The scope of this ranking is broad yet meticulously tailored. Initially, 279,971 scientist profiles across all disciplines were examined, drawn from a diverse array of bibliometric data sources. From this extensive pool, 73 scientists specifically engaged in Materials Science were identified for consideration.
To qualify for inclusion in the ranking, each scientist was required to meet several criteria:
- A minimum D-index of 40, reflecting significant scholarly impact within Materials Science.
- A majority of their tier publications had to be situated within the Materials Science domain.
- Acknowledged awards and professional achievements in the field of Materials Science were also factored into the selection process.
The D-index threshold is dynamically set in increments of 10 according to the estimated total number of scholars active in each discipline. This nuanced approach ensures that the top 1% of leading researchers within each field are included. Additionally, the methodology incorporates a proximity constraint: the difference between a scientist’s overall H-index and their D-index is maintained at 30% or less, enhancing the discipline specificity and relevance of the ranking.
Verification and Evaluation Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team implemented rigorous verification protocols. All scientist profiles were manually reviewed and cross-checked against publications indexed in a wide spectrum of trustworthy sources, ensuring data reliability and confirming alignment with the Materials Science discipline.
While the number of publications in prominent journals and conference proceedings is not a formal criterion influencing ranking position, it serves as an important secondary indicator of a researcher’s substantive contributions to their field.
Ultimately, a researcher’s rank is established using their D-index, derived from the authoritative data from OpenAlex and CrossRef. These sources represent the gold standard of bibliometric information, thereby lending robust credibility to the ranking outcomes.
