A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a discipline-specific adaptation of the traditional H-index. The D-index exclusively factors in papers and citations related to the examined discipline—Materials Science in this case—thus offering a refined measure of impact and productivity that is tailored specifically to the field of study.
Scope of Research and Eligibility Criteria
The ranking process began with an examination of 279,971 scientist profiles aggregated across a diverse array of bibliometric sources encompassing all academic disciplines. From this extensive pool, 263 scientists who specialize in Materials Science were identified and evaluated.
To qualify for inclusion in the ranking, a scientist must meet the following criteria:
- A minimum D-index of 40 within the Materials Science discipline.
- A majority of their tier publications must be categorized within Materials Science.
- Recognition of awards and notable achievements specifically in the field of Materials Science was also taken into consideration as a qualitative factor.
The D-index threshold for selecting top researchers is calibrated in increments of 10, reflecting the estimated size of the scholar population in each discipline. This approach ensures that the ranking consistently integrates the top 1% of leading scholars within Materials Science. Additionally, a proximity threshold of 30% or less between a scientist’s overall H-index and their D-index was applied, ensuring relevance and specialization in the assessed discipline.
Verification and Quality Assurance Practices
Understanding the limitations of raw bibliometric data, the Research.com team performed meticulous manual verification of all scientist profiles considered for this ranking. Each profile was cross-checked against publications indexed in a broad range of trustworthy academic sources to affirm accuracy and consistency.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the ranking, it serves as a valuable secondary signal. This additional metric helps provide insight into the breadth and depth of a scientist’s contribution to materials science research.
The ranking positions are fundamentally established through the D-index calculation derived from data in OpenAlex and CrossRef. We emphasize that these platforms represent the most prominent bibliometric databases available and are curated to uphold the highest standards of reliability within the scientific community.
