Bibliometric data used to devise the citation-based metrics for this ranking were collected as of January 12, 2026. A key metric employed in establishing a scientist’s position within the ranking is the D-index (Discipline H-index), which exclusively considers publication and citation metrics pertinent to the specific discipline under evaluation—in this case, Genetics. The D-index is designed to accurately reflect a researcher’s impact within their field by isolating discipline-specific contributions from their broader scientific output.
Scope of Research and Selection Criteria
The ranking methodology involved an extensive examination of 187,823 scientist profiles aggregated from various bibliometric sources across all scientific disciplines, including a dedicated focus on 10 leading scientists within Genetics in Russia. To qualify for inclusion in the Genetics ranking, a researcher was required to have a D-index of at least 40, with the majority of their tier publications concentrated in the Genetics discipline.
In addition to bibliometric criteria, scientists’ awards and recognized achievements specifically in Genetics were considered to ensure a holistic evaluation of prominence and expertise. The D-index threshold is dynamically adjusted in increments of 10, reflecting the estimated total number of scholars in each discipline, while ensuring that the top 1% of leading researchers are systematically included. Furthermore, the methodology mandates that the proximity between a scientist’s overall H-index and their D-index does not exceed 30%, helping to confirm consistent disciplinary specialization.
Verification Practices and Validity
Recognizing that raw bibliometric data alone cannot fully capture the breadth and quality of scholarly contributions, the Research.com team conducted manual verification of all scientist profiles included in the ranking. This cross-correlation was performed against publications indexed in a wide array of trustworthy sources to confirm authorship and relevance.
While publication volume in prominent journals and conference proceedings is not a direct factor influencing ranking positions, it is acknowledged as a valuable secondary indicator of a researcher’s contribution to the Genetics field.
The final rankings are thus grounded in each researcher’s D-index, derived principally from data provided by OpenAlex and CrossRef—currently the most prominent and respected bibliometric databases accessible to the global research community.
