A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a specialized metric that quantifies research impact based solely on publications and citations within the specified discipline of Microbiology. This approach ensures a focused and discipline-specific assessment of scholarly contributions.
Scope of Research and Qualification Criteria
The ranking encompasses an extensive examination of 187,659 scientist profiles identified across a broad range of disciplines from various bibliometric data sources. Specifically for Microbiology, a total of 1,242 scientists were evaluated. To qualify for inclusion in the ranking, candidates must have achieved a minimum D-index of 40 with the majority of their tier publications falling within the Microbiology field. Additionally, recognition of awards and notable achievements in Microbiology contributed to the evaluation process.
The D-index threshold for each discipline is dynamically set in increments of 10, reflecting the estimated total number of scholars in the field while ensuring that the top 1% of leading scientists are always represented in the list. Furthermore, to emphasize discipline-specific expertise, the difference between a scientist’s general H-index and their D-index must not exceed 30%, guaranteeing alignment of overall scholarly impact with disciplinary performance.
Verification Practices and Methodological Integrity
The Research.com team acknowledges that raw bibliometric data alone cannot fully encapsulate the value of scholarly output. To uphold the integrity of this ranking, all scientist profiles were subjected to rigorous manual verification. Profiles were cross-correlated against publications indexed in an array of trusted sources, ensuring authenticity and accuracy.
While not directly influencing rank position, the number of publications a scientist has in prominent journals and conference proceedings serves as a valuable supplementary indicator of their contribution to the Microbiology research community.
Ultimately, rankings are established using each researcher’s D-index calculated from information aggregated primarily through OpenAlex and CrossRef, which remain among the most comprehensive and credible bibliometric databases available.
