The bibliometric data underpinning the citation-based metrics used in the ranking was collected on January 12, 2026. The ranking methodology centers on each scientist's D-index (Discipline H-index), a refined impact metric that accounts exclusively for publications and citations within the specific discipline under examination—Immunology in this case. This tailored approach ensures that the evaluation reflects a researcher’s influence and contribution strictly within their specialized field.
Scope of Research and Ranking Criteria
The ranking process examined a total of 187,135 scientist profiles sourced across all disciplines, with a focused subset of 9 scientists identified specifically within Immunology. To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 40, ensuring that only researchers with a significant level of impact in Immunology were considered. Additionally, the majority of a qualifying scientist's tier publications had to pertain directly to Immunology, further emphasizing discipline-specific excellence. Where applicable, scientists’ awards and achievements in the field were also factored into the consideration process.
To maintain consistency and relevance across disciplines of varying sizes, the D-index threshold for top researchers is set in increments of 10, correlated with the estimated total number of active scholars in each discipline. This graduated approach guarantees inclusion of approximately the top 1% of leading researchers within the respective fields. Furthermore, a proximity criterion was enforced, whereby the difference between a scientist’s general H-index and their D-index must not exceed 30%, ensuring that the ranking reflects specialized, rather than generalized, scholarly impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or quality, the Research.com team has employed thorough manual verification practices to accompany the algorithmic evaluation. Each scientist profile was cross-validated against a broad array of trustworthy publication sources to confirm the accuracy and relevance of their scientific contributions.
It is important to note that while the number of papers published in prominent journals and conference proceedings is not a direct factor in determining a researcher’s position within the ranking, it is considered a valuable secondary signal of their contribution to Immunology research.
The final ranking positions are exclusively established based on each researcher’s D-index, as derived from data gathered via OpenAlex, CrossRef, and other key data sources. For a detailed explanation of the underlying methodology, please visit our methodology page.
