Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Chemistry Scientists in Morocco Ranking was developed using a combination of comprehensive bibliometric data sources, primarily OpenAlex and CrossRef, supplemented by multiple additional reliable data repositories. Bibliometric data used to calculate citation-based metrics were collected on January 12, 2026. The ranking evaluates researchers based on their D-index (Discipline H-index), a refined bibliometric indicator that focuses exclusively on publication and citation metrics within the examined discipline—in this case, Chemistry. This discipline-specific approach ensures that the ranking reflects expertise and impact accurately within the chosen subject area.
Scope and Criteria of the Ranking
The ranking was derived from an extensive analysis of 279,971 scientist profiles, spanning all disciplines and encompassing 6 distinguished scientists specifically from the field of Chemistry in Morocco. To qualify for inclusion, each scientist’s D-index had to be at least 40, ensuring that only researchers with significant impact within Chemistry were considered. Additionally, a majority of their tier publications needed to be concentrated in the Chemistry domain. Recognized awards and achievements in Chemistry also influenced eligibility and standing within the ranking.
The D-index threshold is calibrated in increments of 10 relative to the estimated total number of scholars within each discipline, guaranteeing that the top 1% of leading scholars are included. Furthermore, to maintain disciplinary focus, a proximity threshold of 30% or less is required between a scientist's general H-index and their D-index, thereby affirming their specialization in Chemistry.
Verification and Validation Practices
Research.com recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output and contribution. To ensure the integrity and credibility of the ranking, all scientist profiles were manually verified and cross-correlated against publications indexed across a wide range of authoritative and trustworthy academic sources. While publication count in prominent journals and conference proceedings is not a direct factor influencing a researcher’s position in the ranking, it serves as a valuable secondary indicator of their research contributions within the Chemistry community.
The final ranking positions are assigned based on each researcher’s D-index calculated from data consolidated through OpenAlex and CrossRef, the most prominent and well-established bibliometric platforms accessible to the global research community.
