Data Sources and Collection
The 5th edition of the Research.com Best Microbiology Scientists in Greece Ranking is founded upon authoritative and comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other trusted bibliometric databases. These sources provide extensive coverage and metadata for scholarly publications across disciplines. The bibliometric data utilized to derive the citation-based metrics were collected as of January 12, 2026. Each scientist’s ranking position reflects their Discipline H-index (D-index), a metric that isolates publications and citation counts pertinent exclusively to the examined discipline—Microbiology in this context—thereby ensuring the evaluation is focused and field-specific.
Scope and Criteria of the Ranking
The scope of this ranking encompasses a rigorous assessment of 187,659 scientist profiles aggregated from diverse bibliometric data sources spanning all scientific disciplines. Within this corpus, 15 scientists specializing in Microbiology were identified and analyzed in detail.
To qualify for inclusion in the ranking, a scientist must meet the following criteria:
- A minimum D-index of 40 within the Microbiology discipline.
- A majority of their tier publications concentrated in Microbiology.
- Recognition of awards and achievements specifically in the field of Microbiology.
The threshold D-index value is calibrated in increments of 10 relative to the total number of scholars estimated per discipline, while ensuring the inclusion of the top 1% of leading researchers. A proximity constraint is also applied, whereby the difference between a scientist’s general H-index and their D-index is kept at 30% or less, maintaining relevance and consistency between their overall and discipline-specific impact.
Verification Processes and Ranking Methodology
The research team is acutely aware that raw bibliometric data alone should not be regarded as an absolute measure of scholarly output. Consequently, all scientist profiles featured in this ranking underwent meticulous manual verification and cross-correlation against an array of reputable sources to validate publication records and disciplinary focus.
While not directly influencing a researcher’s ranked position, the count of papers published in prestigious journals and conference proceedings is recognized as an important secondary indicator of scientific contribution within a given field.
The ranking positions are ultimately based on each researcher’s D-index as compiled from OpenAlex and CrossRef, among the preeminent bibliometric databases accessible to the global research community.
