The position of each scientist within this ranking is determined by their Discipline H-index, termed the D-index, which isolates the assessment to papers and citation metrics strictly within the Genetics discipline. This approach allows for a focused evaluation of scholarly influence that is discipline-specific rather than general.
Scope of Research and Ranking Criteria
Our analysis encompassed profiles for 187,823 scientists identified across a diverse array of bibliometric data sources spanning all academic disciplines. Within the Genetics field, a targeted group of 20 scientists was specifically examined. To qualify for inclusion in this ranking, a scientist must have a D-index of at least 40. In addition, the majority of their tier publications need to be concentrated in Genetics. Consideration was also given to scientists’ awards and achievements within the Genetics domain, adding a qualitative dimension to the quantitative metrics.
The D-index threshold employed to identify top researchers is systematically calibrated in increments of 10 relative to the estimated total number of scholars within each discipline. This methodological design ensures that approximately the top 1% of leading scholars are consistently incorporated across all disciplines included in Research.com rankings. Furthermore, a proximity criterion of 30% or less between a scientist’s general H-index and their D-index is required, ensuring alignment between overall and discipline-specific impact.
Verification Practices and Transparency
The Research.com team acknowledges that raw bibliometric data alone can never serve as an absolute measure of scholarly output or contribution. In recognition of this limitation, all scientist profiles included in the ranking were manually verified. This process involved cross-correlation against publications listed in a broad range of trustworthy and authoritative sources.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position on Research.com, it is nevertheless regarded as a valuable secondary indicator of a scientist’s contributions within their research area.
Ultimately, the ranking position is established by each researcher’s D-index, which is derived from data gathered primarily from OpenAlex and CrossRef—two of the most prominent and widely-recognized bibliometric databases available to the research community.

The Research.com Mission
Research.com’s core mission behind the creation of this ranking is to motivate researchers, companies, and policymakers worldwide to closely examine the trajectories of leading experts in various fields. Our goal is to provide a transparent, rigorously compiled platform where the entire scientific community can identify and recognize who the leading experts are in specific study areas, across different countries, and within research institutions.
By fostering greater visibility of scientific leaders, we aim to support collaboration, inform strategic investment in research, and aid academic institutions in benchmarking excellence against global standards.
