Data Sources and Citation-Based Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Peru Ranking has been meticulously developed using comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data sources. The bibliometric data utilized to derive citation-based metrics was collected on January 12, 2026, ensuring that the ranking reflects the most up-to-date research impact measures available. A scientist’s position in this ranking is determined exclusively by their D-index (Discipline H-index), a discipline-specific adaptation of the traditional H-index that only incorporates papers and citations relevant to the examined field, in this case, Materials Science.
Scope of Research and Eligibility Criteria
The ranking analysis encompassed a total of 279,971 scientist profiles identified across a broad array of bibliometric databases covering all disciplines. Specifically, 1,234 scientists specializing in Materials Science were examined. To qualify for this ranking, a scientist’s D-index is required to be at least 40, with the majority of their tier publications explicitly within the domain of Materials Science. Additionally, recognition of awards and achievements pertinent to Materials Science was factored into the comprehensive evaluation.
The D-index threshold for identifying top researchers is calibrated as an increment of 10 in accordance with the estimated total number of scholars within each discipline, while simultaneously ensuring that the top 1% of leading experts are included in the list. Furthermore, to maintain consistency and relevance, a scientist’s general H-index must exhibit a proximity of 30% or less relative to their D-index, thereby guaranteeing that their broader research impact aligns closely with their discipline-specific contributions.
Verification Practices and Reliability
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute metric for assessing scholarly output. Therefore, every scientist profile included in the ranking underwent rigorous manual verification and was cross-correlated against publications indexed in a wide range of trustworthy sources. While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it is considered a valuable secondary signal of their impact and contribution to Materials Science research.
The final ranking positions are established through the D-index, as calculated from data gathered predominantly from OpenAlex and CrossRef—two of the most authoritative and widely acknowledged bibliometric databases accessible to the global research community.
