The core metric driving the ranking is the D-index (Discipline H-index), which refines the traditional H-index by focusing exclusively on publications and citations within the examined discipline—in this case, Genetics. This discipline-specific approach enables a more accurate reflection of a researcher’s impact and specialization in their field.
Scope of Research and Qualification Criteria
Our analysis examined 187,823 scientist profiles identified through various bibliometric data sources across all disciplines, with a subset of 8 scientists specializing in Genetics from Saudi Arabia specifically evaluated for this ranking.
To qualify for inclusion, a researcher’s D-index had to meet a minimum threshold of 40, with the majority of their tier publications concentrated within the area of Genetics. In addition to bibliometric metrics, a scientist’s documented awards and achievements in Genetics were reviewed to corroborate their research excellence.
The D-index threshold for top researchers is calibrated in increments of 10 relative to the total number of scholars estimated within each discipline, thereby ensuring the incorporation of approximately the top 1% of leading experts. Furthermore, a strict proximity criterion was applied whereby the gap between a scientist's overall H-index and their Discipline H-index must not exceed 30%, reinforcing the focus on specialized expertise rather than general research output.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as an absolute measure of scholarly impact, our research team undertakes rigorous manual verification of all scientist profiles. Each profile is cross-referenced against publications indexed in an extensive array of reputable sources to validate the accuracy and authenticity of the data.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking, it is considered a valuable secondary indicator of a scientist’s contribution to research within Genetics.
The ranking positions are established strictly using each researcher’s D-index derived from OpenAlex and CrossRef, which remain the most prominent and authoritative bibliometric databases accessible to the global research community.
