The bibliometric data used to calculate the citation-based metrics for this ranking were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that focuses exclusively on papers and citation counts within the specific discipline of Materials Science. This approach ensures that the ranking reflects scholarly impact directly relevant to the field.
Scope of Research and Ranking Criteria
The ranking process began by analyzing a total of 279,971 scientist profiles identified across a wide array of bibliometric sources encompassing all academic disciplines. Among these, 2,000 profiles were explicitly classified within the Materials Science domain.
To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 40, with a majority of their high-tier publications concentrated in Materials Science. Additionally, recognition through awards and notable achievements within the field was incorporated as a qualitative factor in the evaluation framework.
The threshold for the D-index is dynamically adjusted in increments of 10 relative to the total number of scholars estimated per discipline. This mechanism is designed to ensure that the top 1% of leading experts in Materials Science are captured in the list. Furthermore, to confirm a researcher’s specialization in the discipline, their general H-index and D-index must exhibit a proximity of no more than 30%, enhancing the specificity of the measure to Materials Science contributions.
Verification Practices and Ranking Methodology
At Research.com, we recognize that raw bibliometric data are not definitive indicators of a scholar’s full research output or impact. Thus, every scientist profile included in the ranking underwent meticulous manual verification. This verification process involved cross-correlation with a broad spectrum of trustworthy publication sources to ensure accuracy and authenticity.
While the number of papers published in prominent journals and conference proceedings does not directly influence the position within the Research.com ranking, it serves as a valuable secondary signal of a scientist’s contribution to their area of expertise.
The final position in the ranking relies on each researcher’s D-index as computed from data primarily aggregated via OpenAlex and CrossRef. These databases represent the most prominent and respected bibliometric resources accessible to the scientific community at large.
