A key metric employed is the D-index (Discipline H-index), which reflects a scientist’s research impact within a specific discipline—here, Genetics. Unlike the general H-index, the D-index exclusively accounts for papers and citation metrics related to the examined discipline. This focused approach ensures that the ranking accurately represents scholarly contributions in Genetics, offering nuanced insight into subject-specific research excellence.
Scope and Criteria of the Ranking
The scope of the ranking encompasses a rigorous examination of 187,823 scientist profiles identified from a wide range of bibliometric data sources across all scientific disciplines. Within the field of Genetics specifically, 17 scientists were carefully evaluated.
To qualify for inclusion in the Genetics ranking, a scientist’s D-index must be at least 40, and the majority of their tier publications must fall within the Genetics discipline. Additionally, a candidate’s awards and achievements relevant to Genetics were taken into account, providing a holistic picture of their scientific stature.
The D-index threshold is calibrated thoughtfully as increments of 10 based on the estimated total number of scholars in each discipline. This methodology ensures that the ranking consistently incorporates the top 1% of leading researchers. Furthermore, to maintain disciplinary relevance, the proximity between a scientist’s general H-index and their D-index must not exceed 30%, thereby emphasizing discipline-focused scholarly excellence.
Additional Verification Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team implemented meticulous manual verification for all scientist profiles included in the ranking. This process involved cross-correlating profiles against publications listed in a wide array of trustworthy and authoritative sources.
While not directly factored into the ranking position, the volume of papers published in prominent journals and conference proceedings serves as an important secondary indicator of a researcher’s contributions to their field.
The final ranking positions are established based on each researcher’s D-index, calculated using data primarily from OpenAlex and CrossRef — the most prominent and authoritative bibliometric databases available to the research community.
