A scientist’s position in the ranking is determined by their D-index (Discipline H-index). This metric uniquely assesses a researcher’s impact within a specific discipline, considering only those papers and citation metrics that fall within the examined field — in this case, Microbiology. The D-index thus offers a focused measure of scholarly influence tailored to the scientist’s core research domain.
Scope of Research and Selection Criteria
In compiling the ranking, a comprehensive examination was conducted encompassing 187,659 scientist profiles identified across all disciplines from a variety of bibliometric data sources. Specifically, for Microbiology, 7 scientists were considered in detail.
- To qualify for inclusion, a scientist's D-index had to be at least 40.
- The majority of the scientist’s tier publications were required to be within the area of Microbiology.
- Recognition of awards and achievements specifically in the field of Microbiology was also factored into the evaluation process.
The threshold for the D-index is adaptively set in increments of 10 based on the estimated total number of scholars in each discipline. This approach ensures that approximately the top 1% of leading scholars in a field are incorporated into the ranking. Additionally, the methodology ensures that the difference between a scientist’s general H-index and their D-index does not exceed 30%, maintaining a close alignment between overall and discipline-specific impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully capture the quality and contribution of scholarly work, the Research.com team rigorously applies manual verification practices. Each scientist profile was individually reviewed and cross-correlated against publications in a wide range of trustworthy and authoritative sources.
While the number of publications in prominent journals and conference proceedings is not a direct factor in determining a researcher’s position within the ranking, it is considered a valuable secondary signal of scientific contribution within the specific area of study.
The final positions in the ranking are established using each researcher’s D-index, as derived from OpenAlex and CrossRef — the leading and most widely recognized bibliometric databases currently accessible to researchers worldwide.
