A scientist’s position within this ranking is determined based on their D-index (Discipline H-index), a metric designed to assess scholarly impact specifically within the discipline of Materials Science. The D-index exclusively considers publications and citation data relevant to this examined field, ensuring the ranking reflects focused academic contributions rather than overall research output.
Scope of Research and Qualification Criteria
In constructing this ranking, an extensive dataset comprising 279,971 scientist profiles aggregated from various bibliometric repositories across all disciplines was initially examined. Within this broad scope, 698 researchers with active profiles in Materials Science were identified and analyzed in detail.
To qualify for inclusion in the ranking, a scientist’s D-index in Materials Science was required to be at least 40. Furthermore, a majority of their top-tier publications needed to be explicitly situated within the domain of Materials Science. Recognition of awards and achievements specific to this field was also incorporated as a qualitative factor to enhance the robustness of the selection process.
The D-index threshold used to define top researchers is adjusted in increments of 10 according to the estimated total number of scholars within each discipline, concurrently ensuring representation of the top 1% of leading experts. Additionally, a proximity criterion mandates that the difference between a scientist’s overall H-index and their Materials Science D-index does not exceed 30%, guaranteeing a focused disciplinary impact rather than inflated general metrics.
Additional Verification Practices
The Research.com team is acutely aware that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. As such, all scientist profiles included in the ranking were subjected to meticulous manual verification. This process involved cross-referencing each researcher’s publications against a broad spectrum of trusted academic sources to validate the integrity and relevance of the data.
While the number of publications in prestigious journals and conference proceedings does not directly influence the ranking position, it remains a valuable secondary indicator of a researcher’s contribution within their field and is considered during manual reviews.
The final positioning in the ranking is primarily established via the D-index calculated from information sourced from OpenAlex and CrossRef—two of the most prominent and reliable bibliometric databases accessible to the scientific community today.
