A scientist's position in this ranking is determined exclusively by their D-index (Discipline H-index), a refined metric which accounts only for publications and citation counts pertinent to the Materials Science discipline under examination. This focused approach allows for a more accurate evaluation of a researcher’s contributions within their specific field.
Scope of Research and Ranking Criteria
The ranking methodology involved examining a large dataset of 279,971 scientist profiles identified across diverse bibliometric data sources spanning all scientific disciplines. Within the realm of Materials Science, 1,254 scientist profiles were scrutinized. To qualify for inclusion, researchers were required to possess a D-index of at least 40, with the majority of their tier publications centrally focused on Materials Science topics.
In addition to citation metrics, consideration was also given to documented awards and achievements specifically tied to the Materials Science field as part of the comprehensive evaluation. The threshold for D-index consideration is dynamically adjusted in increments of 10, relative to the estimated scholar population within each discipline. This ensures that the top 1% of leading experts by impact and relevance are represented on the list.
Moreover, a proximity constraint was applied whereby the difference between a scientist’s overall H-index and their Materials Science D-index remains within 30%, further guaranteeing the ranking accurately reflects a researcher’s core disciplinary expertise.
Verification Practices
Recognizing that raw bibliometric data are not infallible nor exhaustive indicators of scholarly excellence, the Research.com team implemented thorough manual verification and cross-correlation protocols. Each scientist’s profile was individually reviewed and benchmarked against publications sourced from a wide range of trusted scholarly outlets and institutional repositories. This careful vetting strengthens the ranking’s validity and credibility.
While the quantity of papers published in prominent journals and conference proceedings is not a metric directly influencing the position within the Research.com ranking, it is acknowledged as a valuable secondary indicator of a scientist’s contributions to the specialized field of Materials Science.
The final ranking positions are established exclusively through the D-index scores, based on data harvested from OpenAlex and CrossRef — two of the most prominent and well-regarded bibliometric databases accessible to the research community worldwide.
