Data Sources and Citation Metrics
The 5th edition of the Research.com Best Animal Science and Veterinary Scientists in Iran Ranking was developed using a comprehensive collection of bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. The citation-based metrics foundational to this ranking were extracted on January 12, 2026, ensuring currency and relevance of the evaluation. Core to our analysis is the Discipline H-index, or D-index, a refined metric that isolates a researcher's scholarly output and citation impact strictly within the examined discipline of Animal Science and Veterinary. This approach guarantees that only disciplinary-specific contributions influence each scientist’s position in the ranking.
Scope and Selection Criteria
Our evaluation began with a broad survey of 279,971 scientist profiles aggregated from an extensive range of bibliometric databases covering all academic disciplines. Within this corpus, 18 researchers specializing in Animal Science and Veterinary sciences were identified and assessed. To qualify for inclusion, candidates were required to have a minimum D-index of 20, indicative of a substantial citation footprint in their core discipline. Additionally, a majority of their tier publications had to be explicitly within the Animal Science and Veterinary domain.
Consideration was also given to their awards and notable achievements relevant to this field, recognizing scholarly excellence beyond bibliometrics alone. The D-index threshold was calibrated in increments of 10 according to the size of the scholarly population within each discipline, while ensuring that the top 1% of leading experts are consistently captured. Furthermore, a proximity criterion was applied whereby a researcher’s general H-index and their respective D-index should not differ by more than 30%, underscoring that their disciplinary output aligns proportionally with their overall academic performance.
Additional Verification and Methodological Rigor
We acknowledge that no raw bibliometric data is sufficient by itself to definitively evaluate the full breadth of a scholar’s impact. Accordingly, all scientist profiles underwent meticulous manual verification and cross-correlation against publication records sourced from a broad spectrum of authoritative academic databases and trusted outlets. While publication counts in high-impact journals and key conference proceedings do not directly influence a researcher’s rank in the Research.com listing, they represent an important secondary indicator of their scholarly contributions within Animal Science and Veterinary.
The ranking order is ultimately established through each researcher’s D-index derived from data consolidated primarily from OpenAlex and CrossRef, two of the most widely respected and comprehensive bibliometric platforms accessible to the scientific community.
