The bibliometric data utilized for constructing the citation-based metrics was collected on January 12, 2026. The ranking methodology centers on a researcher’s D-index (Discipline H-index), a refined metric that considers only those papers and citations strictly associated with the discipline under examination—in this case, Materials Science—allowing for a more precise assessment of scholarly impact within the specific field.
Scope of Research and Qualification Criteria
This ranking incorporates a comprehensive review of 279,971 scientist profiles drawn from a variety of bibliometric databases spanning all scientific disciplines. Specifically, 2,941 scientists identified as active contributors to the Materials Science field were examined in depth.
To qualify for inclusion, a scientist’s D-index had to be at least 40, reflecting significant scholarly influence. Additionally, the majority of their high-impact publications needed to reside within the domain of Materials Science. Awards and notable achievements in the discipline were also factored into the evaluation process, contributing to a holistic profile of leadership in the field.
The D-index threshold for top researchers is tailored as increments of 10, calibrated according to the total number of scholars estimated in each discipline. This approach ensures inclusion of the top 1% of leading scientists within the field. Furthermore, a proximity criterion requires that the disparity between a scientist’s general H-index and their D-index remains within 30% or less, reinforcing the discipline-specific focus of the ranking.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as an absolute measure of research quality, our team undertakes meticulous manual verification of all scientist profiles. This process includes cross-correlation against publications indexed in a wide array of authoritative and trustworthy sources to safeguard accuracy and reliability.
Although not a direct factor influencing a researcher’s position in the Research.com ranking, the volume of papers published in prominent journals and conference proceedings is considered a valuable secondary indicator of a scientist’s contribution to the advancement of Materials Science.
The ranking position itself is established based on each researcher's D-index, determined through data gathered from OpenAlex and CrossRef. These databases are internationally recognized for their comprehensive and current bibliometric information.
