A university’s position in the ranking is determined by the cumulative D-indexes (Discipline H-index) of its scholars whose main area of publication is Biology and Biochemistry. Importantly, the D-index considers exclusively publications and citation data within the discipline, ensuring discipline-specific excellence is recognized without dilution by cross-disciplinary activity.
Scope of Research Considered
To establish this ranking, a broad scope of research output was rigorously analyzed. Profiles of 279,971 scientists from an array of bibliometric sources were reviewed, with 97,416 scientists from Biology and Biochemistry specifically included in the final assessment. For a scientist to qualify, they must possess a D-index threshold of at least 40, with the majority of their leading publications in Biology and Biochemistry.
Further, consideration was given to awards and significant achievements in Biology and Biochemistry, providing a qualitative dimension to the evaluation. The D-index threshold for identifying top researchers is increased in increments of 10, tailored to the estimated volume of scholars in each discipline, while guaranteeing representation of the top 1% of leading experts. A maximum proximity of 30% is enforced between a scientist’s overall H-index and their D-index, ensuring the focus remains on genuine subject matter expertise. Awards and field-specific distinctions serve as additional qualifying criteria.
Verification Practices
The team behind the Research.com ranking acknowledges the limitations of relying solely on raw bibliometric data. In recognition of this, every scientist profile was subject to manual verification and cross-referenced against publications from numerous authoritative sources. This thorough review significantly increases the ranking's accuracy and reliability.
Though not directly affecting the ranking position, the number of papers published in leading journals and academic conferences is considered a valuable secondary signal of a researcher’s scholarly contribution. Positions within the ranking are established using each researcher’s H-index, according to data from OpenAlex and CrossRef, the most established and widely recognized bibliometric databases available to scholars worldwide.
