A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively incorporates papers and citation data pertinent to the examined discipline—in this case, Microbiology. The use of the D-index allows a focused evaluation of a researcher's impact within their precise field, rather than across their entire body of work.
Scope of the Research and Ranking Criteria
This ranking is based on an extensive review of 187,659 scientist profiles identified from a variety of bibliometric data sources across all scientific disciplines. Within Microbiology specifically, 381 scientists were rigorously examined to identify the most influential leaders in the field.
To qualify for inclusion, a scientist's D-index needed to be at least 40, ensuring only those with significant scholarly contributions were considered. Additionally, a majority of the scientist’s tier publications had to be predominantly in the area of Microbiology. Beyond bibliometric metrics, awards and recognized achievements in Microbiology were also factored into the qualification process, providing greater context and validation of each scientist’s standing within the discipline.
The D-index threshold for recognizing top researchers is dynamically adjusted in increments of 10, based on the total estimated number of scholars within each discipline. This approach guarantees that the ranking includes the top 1% of leading scholars. Furthermore, to ensure discipline-specific impact, a maximum proximity of 30% is maintained between a scientist’s general H-index and their D-index.
Additional Verification Practices
We recognize that raw bibliometric data alone cannot serve as an absolute measure for evaluating scholarly output. Therefore, all scientist profiles included in this ranking were manually verified with thorough cross-correlation against publications from a wide range of trustworthy and authoritative sources. This meticulous process enhances the ranking’s accuracy and credibility.
Although not directly influencing the position of a researcher within the Research.com ranking, the number of publications appearing in prominent journals and conference proceedings is also viewed as a valuable secondary indicator of a scientist’s contribution to the advancement of research within their specific field.
Ultimately, the position in the ranking is established by each researcher's D-index derived from data gathered mainly through OpenAlex and CrossRef, which remain the most prominent and well-established bibliometric databases accessible to the research community.
