A scientist’s position within the ranking is determined by their D-index (Discipline H-index), which is a refined variant of the traditional H-index. The D-index exclusively includes publications and citation metrics pertinent to the examined discipline—in this case, Microbiology—providing a focused and discipline-specific measure of a researcher’s impact and productivity.
Scope of Research and Criteria for Inclusion
In compiling this ranking, a total of 187,659 scientist profiles, spanning all academic disciplines, were initially examined using data from multiple bibliometric sources. From this vast pool, 460 scientists specializing in Microbiology were identified and analyzed in detail.
To qualify for inclusion in the ranking, a scientist had to meet several rigorous criteria:
- Possess a D-index of at least 40, reflecting a high level of influential published work within Microbiology.
- Have the majority of their tier publications concentrated in the field of Microbiology to ensure thematic relevance.
- Demonstrate awards and recognized achievements specifically within the domain of Microbiology.
The D-index threshold is dynamically adjusted in increments of 10 across different disciplines according to the estimated size of each scholarly community. This adaptive threshold is designed to incorporate the top 1% of leading scholars in each discipline while maintaining a meaningful standard of excellence. Additionally, a proximity criterion mandates that the difference between a scientist's general H-index and their D-index should not exceed 30%, thereby affirming a consistent and substantial focus on Microbiology in their research output.
Verification Practices and Ranking Methodology
Recognizing that raw bibliometric data alone cannot fully encapsulate the quality and significance of a scholar’s contributions, the research team has implemented rigorous manual verification procedures. Each scientist’s profile was meticulously cross-correlated against publications in a wide range of trusted sources to ensure accuracy and integrity of the data used.
While the number of publications in prominent journals and high-profile conference proceedings does not directly affect a researcher’s position within the ranking, this information serves as a valuable secondary signal, shedding light on the scientist’s broader influence and recognition within their field.
The ranking positions are ultimately established based on each researcher’s D-index, derived from citation and publication data gathered principally from OpenAlex and CrossRef. These databases are acknowledged for their comprehensive coverage, reliability, and wide acceptance in the scientific community.
