A scientist’s position in the ranking is determined exclusively by their Discipline H-index, or D-index. This metric focuses specifically on papers and citations within the discipline of Materials Science, enabling a targeted and fair assessment of scholarly contributions in the relevant field.
Scope of Research and Eligibility Criteria
To develop an accurate and representative ranking, Research.com examined a total of 279,971 scientist profiles drawn from a variety of bibliometric data sources, spanning all disciplines. Within the specific domain of Materials Science, 17 scientist profiles were identified and analyzed in detail.
For inclusion in this ranking, each scientist must meet a minimum D-index threshold of 40, ensuring that only researchers with significant disciplinary impact are considered. Additionally, a majority of their tier publications must be within the Materials Science domain. Awards and notable achievements in the field were also factored into the consideration process to further validate research excellence.
The D-index threshold is dynamically set in increments of 10 and adjusted based on the estimated number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading researchers in each field. Furthermore, the ranking methodology enforces a proximity criterion whereby the difference between a scientist’s general H-index and their D-index must not exceed 30%, ensuring that disciplinary impact aligns closely with overall scholarly influence.
Verification Practices and Ranking Methodology
The team behind this ranking recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output. Consequently, all scientist profiles were manually verified and thoroughly cross-correlated against publications in a wide range of trustworthy and reputable sources. This meticulous verification process ensures the accuracy and credibility of the profiles included.
While not a direct factor influencing the ranking positions, the number of papers published in prominent journals and high-impact conference proceedings is regarded as a valuable secondary indicator of a researcher’s contributions to Materials Science.
The ranking itself is established solely on the basis of the D-index values derived from carefully gathered data in OpenAlex and CrossRef, two of the most prominent and well-respected bibliometric databases available to the global research community.
