A scientist’s position within the ranking is determined by their D-index (Discipline H-index), an adaptation of the traditional H-index that exclusively considers publications and citations within the specified discipline under examination. This approach allows for a more precise measurement of a researcher’s influence and impact within the field of Materials Science.
Scope of Research and Inclusion Criteria
The ranking examined 279,971 scientist profiles identified across various bibliometric sources, encompassing all disciplines. From this extensive database, 696 scientists specializing in Materials Science were specifically evaluated. To qualify for inclusion in the ranking, scientists were required to have a D-index of at least 40, with a majority of their tier publications firmly rooted in Materials Science.
In addition to publication metrics, awards and notable achievements within the field were also considered as secondary factors to warrant the relevance and contribution of each researcher.
The threshold for the D-index is dynamically set in increments of 10, commensurate with the estimated population size of scholars in each discipline, thereby ensuring that the ranking represents the top 1% of leading experts. Furthermore, a maximum proximity of 30% between a scientist’s general H-index and their discipline-specific D-index is required to maintain methodological consistency and confirm researchers’ focused impact within Materials Science.
Verification Practices and Methodology Transparency
At Research.com, we fully recognize that raw bibliometric data alone cannot serve as an absolute measurement of scholarly output and quality. Consequently, each scientist profile featured in the ranking undergoes meticulous manual verification and cross-correlation against a broad spectrum of reputable sources. This process helps to authenticate publication records and reinforces the integrity of the ranking.
While position in the ranking is determined exclusively by a researcher’s D-index, the number of papers published in prominent journals and conference proceedings is acknowledged as a valuable secondary indicator of scholarly contribution within the discipline.
Our reliance on OpenAlex and CrossRef—the most prominent and widely respected bibliometric databases available to the global research community—further strengthens the credibility of the ranking methodology. For detailed insights into the methods employed in generating these rankings, readers are encouraged to consult our methodology page.
