Each institution’s position in the ranking is determined by the sum of D-indexes (Discipline H-index) of all ranking scholars within an institution, specifically for those whose primary area of publication is in Biology and Biochemistry. The D-index exclusively incorporates publications and citation data relevant to the examined discipline, ensuring that each scholar’s contributions are accurately reflected within the field of Biology and Biochemistry.
Scope of Research and Inclusion Criteria
The assessment underlying the ranking is exhaustive in scale and rigorous in selection. Out of 279,971 scientist profiles identified from a range of bibliometric data sources, 97,416 scientists working specifically in Biology and Biochemistry were analyzed. To ensure the inclusion of only the leading experts, a qualifying D-index threshold of 40 was set for each scientist, with a requirement that the majority of their tier publications are within the area of Biology and Biochemistry.
Additionally, individual awards and achievements in the field were considered in the ranking process. The D-index threshold for consideration among top researchers is dynamically set, increasing in increments of 10 depending on the estimated total number of scholars in each discipline, guaranteeing that approximately the top 1% of scholars are included. A proximity rule of 30% or less between a scientist’s general H-index and their D-index is enforced, further ensuring the disciplinary relevance of each scholar’s work. Recognition of scientist’s awards and achievements in their respective fields is also integrated as a factor in the evaluation process.
Verification Practices and Additional Assurance
The team behind the Research.com ranking recognizes that bibliometric data, while powerful, must not be taken as an absolute measure of scholarly impact. Therefore, profiles of all scientists included in the ranking have been manually verified for accuracy and cross-referenced against an extensive array of trustworthy publication sources. This validation step is essential to mitigate data inconsistencies and to uphold the integrity of the ranking.
While the total number of papers published in prominent journals and conference proceedings is not a direct factor in a scientist’s placement, it is regarded as a valuable secondary signal of a researcher’s contribution to their discipline. Each researcher’s position in the ranking is established according to their H-index, as collected from the well-regarded OpenAlex and CrossRef databases—two of the most widely respected bibliometric data sources globally.
