A scientist’s position within the ranking is determined by their D-index (Discipline H-index). This metric exclusively accounts for publications and citations relevant to the specific discipline under examination—in this case, Microbiology—thereby refining the assessment to reflect expertise and impact strictly within the field.
Scope of Research and Ranking Criteria
The ranking is based on an extensive assessment of 187,659 scientist profiles identified across a spectrum of bibliometric databases and disciplines. Specifically, for the Microbiology discipline, 2 scientists were identified and rigorously evaluated.
To qualify for inclusion, a scientist’s D-index had to meet a minimum threshold of 40, and the majority of their tier publications needed to be in the field of Microbiology. Additionally, their awards and professional achievements within Microbiology were taken into account to provide a more holistic measure of their scientific stature.
It is important to note that the D-index eligibility threshold increments by 10 points relative to the scale of total scholars estimated within each discipline, ensuring that the top 1% of leading experts are consistently incorporated into the ranking. Further, a proximity criterion was applied whereby the difference between a scientist’s overall H-index and their discipline-specific D-index does not exceed 30%, maintaining precision in evaluating discipline-defined impact.
Verification and Validation Practices
The Research.com team acknowledges that raw bibliometric data alone cannot fully capture the breadth and nuances of scholarly contributions. Accordingly, all scientist profiles in the ranking underwent manual verification and were cross-referenced against publications indexed in a wide array of reputable scientific sources.
While the ranking’s positional determination is strictly based on each researcher’s D-index as calculated from data obtained through OpenAlex and CrossRef—two of the most prominent and reliable bibliometric databases available to the research community—it is recognized that the number of publications in prestigious journals and conference proceedings provides an additional valuable, though secondary, indication of a scientist’s contribution within Microbiology.
