All bibliometric data used to compute the relevant metrics for this ranking were collected on January 12, 2026, ensuring the inclusion of the most recent and validated scholarly output and citation information available at the time of analysis.
The position of each scientist within the ranking is determined by their D-index (Discipline H-index), a refined metric that specifically includes only the papers and citation counts relevant to the examined discipline—Immunology in this case—thus providing a focused and discipline-specific measure of research impact.
Scope of Research and Eligibility Criteria
This ranking was created by assessing a broad pool of 187,135 scientist profiles identified from diverse bibliometric data sources spanning all disciplines. Among them, 82 scientists specializing in Immunology were meticulously evaluated.
To qualify for inclusion in the ranking, a researcher was required to meet a minimum D-index threshold of 40, ensuring a significant level of scholarly impact within Immunology. Furthermore, a majority of their tier publications had to be primarily situated in the field of Immunology. Consideration was also given to the scientist’s awards and notable achievements specific to the discipline.
The threshold for the D-index is calibrated as an increment of 10, adjusted according to the estimated total number of scholars within each discipline. This approach guarantees the inclusion of the top 1% of leading researchers, thereby upholding the rigor and exclusivity of the list. Additionally, candidates were screened to ensure a proximity of 30% or less between their general H-index and their D-index, confirming a strong disciplinary focus.
Additional Verification Practices
The Research.com team is acutely aware that raw bibliometric data alone should never serve as an absolute measure to evaluate scholarly output. To address this, we have implemented a careful manual verification process for all scientist profiles included in the ranking. These profiles were cross-correlated against publications indexed in a wide range of trustworthy and authoritative sources to confirm accuracy and authenticity.
While not a direct factor influencing position within the ranking, the volume of papers published in prominent journals and conference proceedings is recognized as a valuable secondary indicator of a scientist’s contribution to the specific area of Immunology, providing additional context and depth to the overall assessment.
The ranking positions are chiefly established using each researcher's D-index, derived from data sourced from OpenAlex and CrossRef — the most prominent and widely respected bibliometric databases readily accessible to the research community globally. We encourage readers to explore our methodology page for a detailed explanation of the evaluation methods and analytical rigor behind the ranking.
Research.com Agenda and Mission
At Research.com, our mission is to inspire and empower researchers, institutions, companies, and policymakers worldwide by illuminating where leading experts are directing their efforts. By providing transparent, thorough, and reliable rankings of top scientists, we facilitate a deeper understanding of who the foremost experts are in specific areas of study, in different countries, or even within particular research institutions.
This ranking reflects a commitment to meticulous research, objective evaluation, and the dissemination of knowledge, serving as a resource for the global scientific community to recognize and engage with outstanding researchers driving the frontiers of Immunology.
