A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that accounts exclusively for papers and citation metrics within the specific discipline under examination—in this case, Materials Science. This targeted approach provides a more accurate reflection of an individual’s impact and contribution to the field.
Scope of Research and Selection Criteria
The ranking’s scope is grounded in the meticulous examination of 279,971 scientist profiles aggregated from an array of bibliometric data sources, covering all disciplines comprehensively. Within this data set, 163 scientists specialized in Materials Science were specifically evaluated.
To qualify for inclusion in the ranking, a scientist must demonstrate a D-index of at least 40, with the majority of their tier publications focused within the Materials Science domain. Additionally, significant awards and recognized achievements in the field were factored into the evaluation process, underscoring excellence beyond bibliometrics.
The D-index threshold employed for consideration is calibrated in increments of 10, depending on the estimated total number of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading researchers, maintaining the ranking’s rigor and exclusivity. Furthermore, a proximity criterion is applied where the difference between a scientist's overall H-index and their Materials Science-specific D-index does not exceed 30%, which helps verify the researcher’s primary engagement in the material sciences discipline.
Additional Verification Practices
While recognizing the value of raw bibliometric data, the team responsible for developing this ranking acknowledges its inherent limitations as an absolute measure of scholarly output. Therefore, every scientist profile was manually verified and cross-correlated against publications listed in a diverse range of highly reputable sources. This careful curation ensures the reliability and credibility of the ranking.
Although not a direct factor in determining a researcher’s rank, the number of publications in recognized leading journals and conference proceedings is regarded as a valuable secondary signal of a scientist’s contribution and visibility in the field.
The ranking’s core metric, the D-index, is established exclusively from information collected through OpenAlex and CrossRef, offering a consolidated bibliometric foundation trusted by the global research community.
