Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Microbiology Scientists in Korea Ranking has been developed using data primarily sourced from OpenAlex and CrossRef, complemented by multiple other reputable bibliometric data sources. The comprehensive bibliometric information was collected on January 12, 2026, ensuring that the citation-based metrics reflect the most recent and relevant scientific outputs. The core metric employed to determine each scientist’s ranking is the D-index (Discipline H-index), a refined bibliometric indicator which exclusively considers papers and citation impact within the specific discipline of Microbiology. This approach ensures that the evaluation is focused and representative of a researcher’s contribution to the discipline under study.
Scope and Selection Criteria
A total of 187,659 scientist profiles identified across a broad spectrum of bibliometric databases were analyzed spanning all scientific disciplines. Within this extensive dataset, 36 scientists specializing in Microbiology were specifically examined for inclusion in this ranking. To qualify, a scientist was required to have a D-index of at least 40, with a majority of their tier publications concentrated in the area of Microbiology. In addition to this quantitative threshold, qualitative aspects such as awards and significant achievements in Microbiology were also considered as part of the evaluation process.
The D-index cutoff is dynamically set in increments of 10 based on the estimated total number of scholars within each discipline, ensuring that the top 1% of leading experts are consistently represented. Furthermore, the methodology enforces that the proximity between a scientist’s overall H-index and their discipline-specific D-index does not exceed 30%, guaranteeing a strong disciplinary focus in the rankings.
Verification and Validation Procedures
The researchers responsible for assembling the ranking recognize that raw bibliometric data alone do not provide a comprehensive assessment of a scholar’s research impact. Accordingly, all scientist profiles underwent manual verification processes. These profiles were cross-checked against publications across a range of trustworthy and authoritative academic sources to validate accuracy and authenticity.
While the number of publications in high-impact journals and conference proceedings is not a direct factor in determining a researcher’s rank within Research.com, this metric offers valuable secondary insight into their scientific contributions within Microbiology.
The position in the ranking firmly rests on each researcher’s validated D-index, underpinned by data from OpenAlex and CrossRef—the most prominent bibliometric databases currently accessible to the global research community.
