A researcher’s position within the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only those publications and citation metrics specific to the examined discipline—in this case, Materials Science. This focus facilitates a more precise and relevant evaluation of scientific contributions within the field.
Scope of Research and Qualification Criteria
Our assessment encompassed a total of 279,971 scientist profiles identified across multidisciplinary bibliometric databases. Within this broad dataset, 2,000 scientists specializing specifically in Materials Science were thoroughly examined.
To qualify for inclusion in the ranking, a number of stringent criteria were applied:
- A minimum D-index of 40 was required.
- The majority of a scientist’s tier publications had to be situated within the Materials Science discipline.
- Awards and recognized achievements relevant to Materials Science were also taken into account as supplementary indicators of excellence.
The D-index thresholds applied to consider top researchers are set as increments of 10 based on the estimated total number of scholars within each discipline. This approach guarantees that the top 1% of leading scholars in the field are incorporated. Furthermore, to maintain disciplinary consistency, a proximity threshold of 30% or less between a scientist’s overall H-index and their D-index was required, ensuring alignment between general and discipline-specific research performance.
Verification Practices and Transparency
The team behind this ranking acknowledges the inherent limitations of relying exclusively on raw bibliometric data as an absolute measure of scholarly output. To address this, each scientist's profile underwent rigorous manual verification and cross-correlation against their published works across a broad spectrum of trustworthy, peer-reviewed journals and reputable conference proceedings.
While not a direct factor in determining placement within the Research.com ranking, the quantity of publications in prominent journals and key conference proceedings serves as a valuable secondary signal of research contribution and impact within the specific scientific domain.
Positions in the ranking were ultimately established using each researcher’s D-index, derived from the meticulously curated data in OpenAlex and CrossRef—the most prominent and trusted bibliometric databases accessible to the global research community.
