A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a specialized metric that isolates and evaluates their research output and impact strictly within the Materials Science discipline. This ensures the ranking reflects contributions specifically pertinent to the field under examination, rather than a general scholarly profile.
Scope of Research Considered
For this edition, a total of 279,971 scientist profiles across all disciplines were analyzed based on aggregated bibliometric data from diverse sources. Within the focused domain of Materials Science, 2 scientists were identified who met the ranking's exacting criteria. To qualify, a scientist must have a D-index of at least 40, underscoring a substantial and influential body of research within the discipline. Additionally, the majority of their high-impact publications must reside specifically within Materials Science, supplemented by recognized awards and professional achievements in this field.
The D-index threshold is calibrated in increments of 10, tailored to the estimated population size of scholars in each discipline. This approach guarantees that the top 1% of leading experts—those making the most significant academic contributions—are captured in the list. Furthermore, to maintain disciplinary relevance, a proximity criterion is enforced, whereby a scientist’s general H-index and their D-index should diverge by no more than 30%.
Additional Verification Practices
The Research.com team acknowledges that raw bibliometric data, while indispensable, cannot serve as an absolute measure of scholarly contribution. Accordingly, all candidate profiles were subjected to rigorous manual verification processes. This included cross-correlation against publications and citations recorded in a multitude of trustworthy and authoritative sources to validate accuracy and contextual relevance.
Although the number of papers published in prestigious journals and leading conference proceedings does not directly impact ranking positions, it is recognized as a valuable secondary indicator of a researcher’s active engagement and influence in their specific scientific area.
As stated, the position in the ranking strictly derives from each researcher’s discipline-specific D-index, computed from data aggregated via OpenAlex and CrossRef. These databases provide a robust, transparent foundation for the metrics used.
