Data Sources and Ranking Methodology
The 4th edition of the Research.com Best Biology and Biochemistry Universities in India Ranking is based on comprehensive analyses of scholarly output data derived primarily from OpenAlex and CrossRef, complemented by multiple other data sources. The bibliometric data necessary for devising the citation-based metrics that underpin the ranking were compiled and collected as of November 27, 2024. Each institution's position in the ranking was determined by aggregating the D-indexes (Discipline H-index) of all ranking scholars affiliated with that institution, provided their primary area of publication is Biology and Biochemistry. Notably, the D-index metric accounts exclusively for discipline-specific publications and citation data, ensuring subject-specific relevance and accuracy.
Scope of Research and Analysis
The ranking was established through the examination of 279,971 scientist profiles identified from a broad spectrum of bibliometric data sources. Of these, 97,416 scientists specializing in Biology and Biochemistry were specifically analyzed. To qualify, a scientist needed a D-index threshold of at least 40, and the majority of their primary publications had to fall within Biology and Biochemistry. In addition, a scientist’s awards and achievements in the discipline were also considered.
The D-index threshold for inclusion among top researchers was incrementally set (by 10-point steps) depending on the estimated total number of scholars in each discipline, thereby ensuring that the top 1% of leading scholars per field were recognized. There was a further requirement that the proximity between a scientist’s general H-index and their discipline-specific D-index was no more than 30%, ensuring focus and impact within Biology and Biochemistry. Beyond bibliometric data, scientific recognition through awards and career achievements also factored into the analysis.
Verification and Quality Assurance
In recognition of the limitations inherent in raw bibliometric data, Research.com implemented rigorous manual verification practices. Every scientist profile was manually reviewed and cross-referenced with publication records available from established and trustworthy sources. While not directly influencing ranking positions, the volume of articles published in top-tier journals and conference proceedings was considered a valuable secondary indicator of scientific contribution in the field.
Final rankings were determined using each researcher's H-index calculated from data obtained from OpenAlex and CrossRef, the two most reliable and widely recognized bibliometric databases available to the research community.
