The bibliometric data utilized to devise the citation-based metrics were systematically collected on January 12, 2026. The ranking positions are determined using a researcher's D-index (Discipline H-index), a refined metric that selectively includes only papers and citation data relevant to the specific discipline under evaluation—Animal Science and Veterinary in this case. This approach ensures that each scientist’s impact is measured accurately within their core field of expertise.
Scope of Research and Qualification Criteria
Our ranking process involved examining 279,971 scientist profiles gathered from a variety of bibliometric data sources across all disciplines, with a focused subset of 5 scientists identified specifically within the Animal Science and Veterinary domain. To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 20. Additionally, the majority of their tier publications had to be concentrated in the Animal Science and Veterinary area. Beyond quantitative metrics, consideration was also given to a scientist’s awards and recognized achievements in this field.
The D-index threshold for top researchers is set in increments of 10 according to the estimated total number of scholars in each discipline, ensuring that approximately the top 1% of leading scholars are incorporated into the list. Furthermore, a strict proximity criterion is enforced, whereby the gap between a scientist’s overall H-index and their discipline-specific D-index must be 30% or less. This safeguards that ranked researchers have a substantial and consistent record within the specified field.
Additional Verification and Methodological Rigor
At Research.com, we are keenly aware that raw bibliometric data alone can never serve as an absolute measure of scholarly output or impact. Consequently, every scientist profile included in this ranking was subjected to manual verification. This process involved cross-referencing profiles against publications indexed in numerous trustworthy and authoritative sources.
While the number of papers published in leading journals and conference proceedings is not a direct factor influencing a researcher’s ranking position, it is regarded as a valuable complementary indicator of contribution to specific scientific disciplines.
The ranking positions are ultimately established using the researchers’ D-indices, calculated from carefully curated data within OpenAlex and CrossRef — two of the most prominent, transparent, and well-regarded bibliometric databases accessible to the global research community.
