A scientist’s position within this ranking is determined using the D-index (Discipline H-index), a refined measure that captures a researcher’s citation impact specifically within the Materials Science discipline. Unlike a general H-index, the D-index filters publications and citations exclusively related to the examined research area, providing a focused and meaningful assessment of disciplinary contributions.
Scope of Research and Qualification Criteria
To build this ranking, a total of 279,971 scientist profiles identified across a variety of bibliometric data sources covering all academic disciplines were scrutinized. From this extensive pool, only 2,051 scientists specifically affiliated with Materials Science were considered for inclusion. Qualification for the ranking mandates that a researcher’s D-index be at least 40, ensuring that only scientists with a substantial impact in Materials Science are recognized.
Furthermore, the majority of an examined scientist’s tier publications must be directly related to Materials Science, reinforcing the disciplinary focus of the ranking. Recognition of a scientist’s awards and notable achievements within the field was also integrated as an important factor, adding qualitative insight beyond citation metrics.
The D-index threshold is dynamically calibrated in increments of 10 based on the estimated number of scholars in the discipline, thereby guaranteeing inclusion of the top 1% of leading researchers. In addition, candidates were selected to have a proximity of 30% or less between their overall H-index and their Materials Science-specific D-index, to maintain alignment between their general and discipline-specific research impact.
Verification Practices and Methodology Transparency
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the researchers responsible for this ranking conducted a thorough manual verification of all scientist profiles. This process involved cross-correlating publication records against a broad spectrum of trustworthy and authoritative sources to confirm the accuracy and integrity of the data.
Although not a determinant of ranking position, the number of papers published in prominent journals and leading conference proceedings is considered a valuable secondary signal that reflects a scientist’s influence and contribution within Materials Science.
The ranking positions are fundamentally established through each researcher’s D-index as computed from OpenAlex and CrossRef data. These sources offer transparent, reliable, and up-to-date citation information crucial for robust bibliometric evaluation.
