A scientist’s position within the ranking is determined exclusively based on their D-index (Discipline H-index), a refined bibliometric measure that considers only the publications and citation metrics pertinent to the specific discipline under examination—in this case, Materials Science. This approach ensures that the ranking reflects expertise and impact strictly within the relevant domain.
Scope of Research and Eligibility Criteria
The ranking was developed by examining profiles of 279,971 scientists identified through a variety of bibliometric sources across all scientific disciplines. Within this broad pool, 10 scientists specialized in Materials Science were closely evaluated. To qualify for the ranking, each candidate was required to have a D-index of at least 40, ensuring a minimum level of disciplinary impact and productivity. Furthermore, the majority of each scholar’s tier publications needed to be clearly associated with Materials Science.
In addition to bibliometric thresholds, the scientists’ awards and notable achievements within the field of Materials Science were considered as complementary factors to substantiate their standing. The D-index threshold for recognition is dynamically calibrated in increments of 10 depending on the estimated total number of scholars within each discipline, thereby guaranteeing inclusion of the top 1% of leading experts in the respective fields. An additional criterion stipulated that the proximity between a scientist’s overall H-index and their specific D-index should be 30% or less, ensuring the researcher’s core expertise alignment within Materials Science.
Additional Verification Practices
The Research.com team is acutely aware that raw bibliometric data alone cannot serve as a definitive measure of scholarly output. Consequently, all scientist profiles included in the ranking underwent meticulous manual verification. These verifications involved cross-correlation of publication records against a wide array of trustworthy and authoritative sources to confirm accuracy and relevance.
Although the quantity of papers published in prominent journals and conference proceedings does not directly influence the ranking score, it is regarded as a valuable secondary signal of a scientist’s contribution to their specific research area. Ultimately, the position in the ranking is established based on the verified D-index metrics derived from OpenAlex, CrossRef, and complementary data repositories.
