Data Sources and Metrics
The 5th edition of the Research.com Best Genetics Scientists in Qatar Ranking is primarily based on bibliometric data aggregated from reputable sources, notably OpenAlex and CrossRef, complemented by multiple additional bibliometric databases. These sources provide comprehensive and up-to-date citation data crucial for constructing objective and data-driven rankings. The bibliometric data employed to devise the citation-based metrics was collected on January 12, 2026, ensuring the inclusion of the most recent scholarly outputs and citation counts available at the time of evaluation.
A key metric used to determine a scientist's position in the ranking is the D-index (Discipline H-index). Unlike the traditional H-index, the D-index is specifically calculated by including only the academic papers and their citations that fall strictly within the examined discipline, providing a focused and accurate measure of research impact in Genetics.
Scope of Research and Qualification Criteria
This edition of the ranking examined 187,823 scientist profiles identified from diverse bibliometric data sources across all scientific disciplines. Within the field of Genetics specifically, 2 scientists met the predefined criteria for inclusion. To qualify for consideration in the Genetics ranking, a scientist must have a D-index of at least 40, reflecting a high level of research influence within the discipline. Furthermore, a majority of the scientist's tier publications must be concentrated in the area of Genetics, ensuring alignment with the domain focus.
Beyond bibliometric measures, awards and notable achievements in Genetics were incorporated as additional qualitative factors in the evaluation process. The threshold for D-index consideration is set in increments of 10 according to the estimated total number of scholars within each discipline, assuring that the ranking consistently includes the top 1% of leading researchers in the field. Moreover, to maintain disciplinary consistency, a scientist’s general H-index and D-index values must not differ by more than 30%, ensuring the D-index reflects a genuine specialization rather than a diluted impact across multiple disciplines.
Verification and Methodological Rigor
We recognize that raw bibliometric data, while essential, is never intended to serve as an absolute measure of scholarly output or research quality. In acknowledgment of this, all scientist profiles included in the ranking underwent meticulous manual verification. Researchers’ publication records and credentials were cross-correlated with a broad spectrum of trustworthy academic sources to confirm accuracy and relevance.
While the number of publications in prominent journals and conference proceedings does not directly influence the positioning in the Research.com ranking, it remains a valuable secondary indicator of a scientist’s contribution and standing within the Genetics research community.
The ranking positions are fundamentally established using each researcher's D-index as determined from data aggregated by OpenAlex and CrossRef—the two most prominent and widely recognized bibliometric databases accessible to the global research community.
