Data Sources and Citation Metrics
The 5th edition of the Research.com Best Materials Science Scientists in Morocco Ranking is grounded primarily on comprehensive bibliometric data obtained from OpenAlex and CrossRef, complemented by multiple other reputable data sources within the research community. The citation-based metrics that form the foundation of this ranking were meticulously collected on January 12, 2026. A researcher’s position in this ranking is determined by their D-index (Discipline H-index), a metric that exclusively considers papers and citation metrics relevant to the examined discipline, in this case, Materials Science. This discipline-specific focus ensures that the ranking accurately reflects scientific contributions within the precise field.
Scope of Research Considered
The ranking methodology encompassed the examination of 279,971 scientist profiles extracted from a wide variety of bibliometric data sources, spanning all research disciplines. Specifically, for Materials Science, 4,000 scientists were analyzed in detail. To qualify for inclusion in this ranking, a researcher must have a D-index of at least 40, with the majority of their tier publications concentrated in the area of Materials Science. Additional considerations included recognized awards and achievements within the field, which serve as supportive evidence of a scientist’s impact.
The D-index threshold is adaptively set in increments of 10, depending on the estimated total number of scholars in each discipline. This approach ensures inclusion of the top 1% of leading researchers while maintaining rigor and relevance. Furthermore, to maintain discipline specificity, the proximity between a researcher’s overall general H-index and their D-index is capped at 30% or less, reinforcing that their primary contributions are rooted in Materials Science.
Verification Practices and Methodological Transparency
Understanding the inherent limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com analysis team has implemented thorough manual verification processes. Each scientist profile was carefully scrutinized and cross-correlated against publications listed in a broad array of trustworthy academic sources to verify accuracy and authenticity.
While not directly influencing the ranking position, the number of papers published in prestigious journals and conference proceedings is acknowledged as a meaningful secondary signal indicating a scientist’s contribution and influence within the Materials Science community.
The ranking positions are ultimately established based on researchers’ D-indices, derived from the most prominent and well-regarded bibliometric databases available—OpenAlex and CrossRef. These resources provide comprehensive, authoritative data essential for this evaluation.
