A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that captures research impact strictly within the examined discipline by accounting only for papers and citation data relevant to that field. This tailored approach ensures that rankings accurately reflect a researcher’s influence specific to chemistry.
Scope of Research and Inclusion Criteria
Across all scientific disciplines, a total of 279,971 scientist profiles were examined, drawn from an extensive compilation of bibliometric data sources. Specifically, within the domain of Chemistry, 16 scientists based in the United Arab Emirates were evaluated for inclusion.
To qualify for this ranking, a scientist must meet a minimum D-index threshold of 40, ensuring that only researchers with substantial and significant citation impact in Chemistry are considered. Additionally, the majority of their tier publications must pertain explicitly to the chemistry discipline. Recognition of awards and notable achievements within the field also played an instrumental role in validating their candidacy in the ranking.
The threshold for the D-index is calibrated with an incremental step size of 10 relative to the estimated total number of scholars in each discipline. This methodical adjustment guarantees that the top 1% of leading scientists are captured in the ranking. Moreover, a proximity of 30% or less between a scientist’s overall H-index and their D-index is required to ensure high alignment between general impact and discipline-specific contributions.
Additional Verification Practices
We recognize that raw bibliometric data alone can never serve as an absolute or exclusive tool in evaluating the multifaceted output of scholars. Therefore, beyond quantitative metrics, all scientist profiles included in this ranking were manually verified and cross-correlated with publications indexed in a diverse array of trustworthy and authoritative sources. This rigorous verification enhances the credibility and validity of the ranking results.
While not directly affecting a researcher’s position in the ranking, the volume of papers published in leading journals and conference proceedings is regarded as a valuable secondary indicator of scholarly contribution within a specific area of science. The D-index remains the principal metric guiding the ranking, calculated specifically using data from OpenAlex and CrossRef.
