Data Sources and Citation Metrics
The 5th edition of the Research.com Best Immunology Scientists in Iran, Islamic Republic Of Ranking is primarily based on comprehensive bibliometric data aggregated from leading sources including OpenAlex and CrossRef, complemented by multiple other reputable databases. These sources collectively provide extensive coverage of publication and citation records, ensuring a robust foundation for analysis. The bibliometric data used to calculate the citation-based metrics for this ranking were collected on 2026-01-12, ensuring that the evaluation reflects the most current scholarly impact available at the time of compilation.
A scientist’s position in the ranking is determined by their D-index (Discipline H-index), which differs from a traditional H-index by exclusively incorporating papers and citation metrics pertinent to the examined discipline—in this case, Immunology. This discipline-specific approach provides a focused measure of each researcher’s influence and productivity within the field.
Scope of Research and Inclusion Criteria
This ranking examines a total of 187,135 scientist profiles identified through an extensive aggregation of bibliometric data sources spanning all academic disciplines. Specifically within Immunology, 5 scientists who meet the qualifying criteria are featured. To qualify for inclusion, a scientist must have a D-index of at least 40, reflecting a significant body of impactful work in the field.
Additionally, a majority of each qualifying scientist’s tier publications must be categorized within Immunology. Awards and professional achievements in this domain also serve as supporting factors in the assessment process. The D-index threshold is calibrated as an increment of 10 based on the estimated total number of researchers within each discipline, ensuring that the top 1% of leading scholars are consistently recognized. Furthermore, to maintain relevance and rigor, the proximity between a scientist’s general H-index and their D-index is required to be 30% or less, reinforcing discipline-specific expertise alignment.
Additional Verification and Methodological Rigor
The team behind this ranking acknowledges that raw bibliometric data alone cannot perfectly capture the multifaceted contributions of researchers. Therefore, all scientist profiles underwent manual verification and were cross-correlated against publications indexed in a broad range of trusted academic sources. While the number of papers in prominent journals and conference proceedings is not a direct factor in the ranking position, it constitutes a valuable secondary signal reflecting a scholar’s overall contribution to advancing Immunology.
Importantly, the final ranking positions are established exclusively by each researcher's D-index as derived from data collected via OpenAlex and CrossRef, the most prominent and authoritative bibliometric databases accessible to the global research community.
