A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that accounts exclusively for papers and citation metrics within the examined discipline—Chemistry. The D-index thus provides a focused evaluation of a researcher’s impact and productivity specifically in the chemistry domain, avoiding distortions from outputs in unrelated fields.
Scope and Criteria of Research Evaluation
The ranking process began by examining 279,971 scientist profiles drawn from a diverse array of bibliometric data sources across all disciplines. Within this comprehensive dataset, 6 scientists specializing in Chemistry in Morocco were identified and analyzed in depth.
To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 40, ensuring a threshold of substantial research impact in Chemistry. Additionally, the majority of a qualifying researcher’s tier publications had to be directly linked to the field of Chemistry. Beyond bibliometrics, scientists’ awards and notable achievements within Chemistry were also considered as supplementary factors reflecting their contribution to the discipline.
The D-index threshold for each discipline is calibrated in increments of 10, relative to the discipline’s estimated total number of scholars. This dynamic threshold ensures that the top 1% of leading researchers are captured within the ranking, maintaining an exclusive and prestigious list of top Chemistry scientists. Furthermore, the methodology includes a proximity filter requiring that the gap between a scientist’s general H-index and their Chemistry-specific D-index not exceed 30%, thereby confirming the researcher’s relevant and focused expertise within the discipline.
Additional Verification and Methodological Rigor
Understanding that raw bibliometric data alone is insufficient to fully capture the value and quality of scientific output, the ranking team carried out meticulous manual verification of all scientist profiles. Each profile was cross-correlated against publications in a broad selection of trustworthy and high-quality sources, ensuring consistency and accuracy in authorship and disciplinary relevance.
While a researcher’s rank is solely determined by their D-index derived from OpenAlex and CrossRef data, the total number of papers published in prominent journals and conference proceedings is also reviewed as a valuable secondary indicator of scholarly contribution in Chemistry.
OpenAlex and CrossRef were selected due to their expansive coverage, transparent methodologies, and wide adoption in the global academic community, making them the most prominent and dependable bibliometric databases available for this ranking exercise.
