Bibliometric data used to calculate the citation-based metrics were gathered on January 12, 2026. The positioning of each scientist in the ranking is determined by their D-index (Discipline H-index), a metric designed to reflect a researcher's impact specifically within their discipline. This index selectively includes only those papers and citation records pertinent to the examined field of Microbiology, providing a more focused assessment of a scientist's contribution within this domain.
Scope of Research and Qualification Criteria
The ranking is based on an extensive evaluation of 187,659 scientist profiles drawn from a diverse array of bibliometric data sources across all academic disciplines. Within this broad survey, 2 scientists specializing in Microbiology in the United Arab Emirates were rigorously examined for inclusion.
To qualify for the ranking, a scientist’s D-index must be at least 40, ensuring a minimum threshold of scholarly impact specific to Microbiology. Additionally, the majority of a qualifying scientist’s tier publications must pertain directly to the field of Microbiology. Beyond bibliometric performance, researchers’ awards and notable achievements in the discipline were also taken into consideration, supplementing the quantitative data with qualitative recognition.
The D-index threshold for consideration is dynamically set in increments of 10 based on the total estimated number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading scholars while accounting for discipline size variations. Furthermore, to maintain consistency and discipline focus, a proximity criterion of 30% or less is required between a scientist’s general H-index and their D-index.
Verification Practices and Ranking Methodology
Understanding the inherent limitations of raw data, the researchers behind this ranking have instituted thorough manual verification protocols. Each scientist’s profile was carefully reviewed and cross-referenced against publications listed in a wide range of trustworthy, independent sources to enhance data reliability and ensure accuracy.
While not a direct factor influencing ranking placement, the number of publications in prominent journals and key conference proceedings is recognized as a valuable secondary indicator of a scientist’s substantive contribution to their field.
Ultimately, ranking positions are assigned based on the D-index calculated from data primarily sourced from OpenAlex and CrossRef, the two foremost bibliometric databases supporting the scholarly community worldwide.
