A researcher's position in the ranking is determined by their Discipline H-index (D-index), a refined variant of the traditional H-index that exclusively incorporates papers and citation counts pertinent to the examined discipline—Materials Science in this case. This tailored metric ensures that the ranking authentically reflects a scientist’s impact within their specific field of expertise.
Scope of Research and Inclusion Criteria
The ranking analysis encompasses a broad dataset, initially examining 279,971 scientist profiles identified across diverse bibliometric sources spanning all academic disciplines. From this extensive pool, 3,459 scientists specializing in Materials Science were isolated for detailed evaluation.
To qualify for inclusion in this ranking, a scientist is required to have a D-index of at least 40. Furthermore, the majority of their tier publications must be concentrated in the area of Materials Science, ensuring disciplinary relevance. Consideration is also given to the individual’s awards and achievements specifically within the Materials Science community.
The threshold for the D-index is dynamically adjusted in increments of 10, reflecting the total estimated number of scholars within each discipline, while simultaneously guaranteeing that the top 1% of leading researchers in the field are incorporated into the list. Additionally, we maintain a proximity limit whereby the difference between a scientist’s general H-index and their D-index does not exceed 30%, thus ensuring that researchers included possess a significant focus on Materials Science relative to their overall scholarly output.
Verification and Validation Procedures
Recognizing the inherent limitations of raw bibliometric data as a sole evaluative tool, the Research.com team has adopted rigorous manual verification techniques to augment the accuracy and reliability of the ranking. Each scientist profile was meticulously cross-correlated against publications indexed in multiple trustworthy sources to confirm authenticity and disciplinary alignment.
While not directly influencing the ranking position, the number of published papers in premier journals and conference proceedings serves as a valuable secondary signal of a scientist’s substantive contribution to the field of Materials Science.
The final ranking positions are established based on each researcher’s D-index, compiled from the most prominent databases—OpenAlex and CrossRef—trusted by the global research community for their comprehensive and up-to-date bibliometric information.
