Institutional positions in the ranking are determined based on the aggregate D-indexes (Discipline H-index) of all qualifying scholars affiliated with a given institution, focusing exclusively on those whose primary area of publication is Biology and Biochemistry. The D-index includes only publications and citation data specific to the evaluated discipline, ensuring that cross-disciplinary publication impact does not distort the results.
Scope of Research: Ranking Coverage and Criteria
For this edition, an extensive dataset comprising 279,971 scientist profiles was meticulously examined, sourced from a wide array of bibliometric databases. Of these, 97,416 scientists with a primary focus in Biology and Biochemistry were specifically analyzed as part of the ranking process.
To ensure high standards and relevance, the threshold for the D-index qualification was set at 40, and only those scientists whose majority of publications fall within Biology and Biochemistry were considered. Additional recognition was given to scientists with significant awards and achievements in the field. Importantly, the D-index eligibility for consideration among leading researchers is dynamically set as an increment of 10, contingent on the total number of scholars within each discipline, thereby consistently retaining the top 1% of researchers in the discipline ranking.
A further criterion stipulates that a scientist's D-index should be within a 30% proximity of their general H-index to ensure discipline-relevance of their scholarly output. Alongside quantitative bibliometric indicators, the recognition of scientist’s awards and achievements in Biology and Biochemistry was also factored into evaluation.
Rigorous Verification and Evaluation Practices
Recognizing the limitations of raw bibliometric data, the creators of the ranking place a strong emphasis on manual verification. Each scientist profile was carefully reviewed and cross-referenced against publications in a large number of highly trusted sources. This diligent process ensures that the ranking reflects a reliable and valid assessment of scholarly achievement.
While factors such as the number of papers published in high-impact journals and major conference proceedings do not directly influence a scientist’s position in the Research.com ranking, they remain a valuable secondary indicator of a researcher’s contribution to their field and should be considered by those using the ranking.
A scholar’s ranking position is calculated based on their discipline-specific H-index data, as retrieved from OpenAlex and CrossRef—two of the most prominent, well-regarded bibliometric databases in the global research community.
