All citation-based metrics utilized to devise this ranking were gathered on January 12, 2026, guaranteeing a current and precise snapshot of scientific impact. A researcher’s position in the ranking is determined by their D-index (Discipline H-index), a discipline-specific adaptation of the traditional H-index that exclusively considers papers and citation metrics within the field of Immunology. This approach allows for a more focused and relevant assessment of expertise and influence within the specialized discipline.
Scope and Criteria of Research Assessment
The ranking’s scope is grounded in a thorough examination of 187,135 scientist profiles sourced from a variety of bibliometric datasets, encompassing all scientific disciplines. Within this extensive dataset, 1 scientist profile specifically related to Immunology in Iceland was identified and analyzed for inclusion in this ranking.
To qualify for the Best Immunology Scientists ranking, each scientist must meet stringent criteria. A minimum D-index of 40 is required, reflecting substantial research output and citation impact pertinent to Immunology. Furthermore, the majority of a scientist's tier publications must be classified under Immunology, ensuring domain-specific relevance. Recognition of a scientist’s awards and other notable achievements in Immunology also contributed qualitatively to their consideration.
The threshold for the D-index is dynamically adjusted, increasing by increments of 10 relative to the estimated total number of scholars in each discipline. This ensures that the ranking systematically incorporates the top 1% of leading experts within each field. Additionally, to maintain a focus on discipline-specific impact, a maximum proximity of 30% or less is required between a scientist's general H-index and their D-index, thereby emphasizing specialization while recognizing broader research contributions.
Additional Verification and Methodological Rigor
Our team appreciates that raw bibliometric data alone can never fully encapsulate the breadth and quality of scholarly output. In recognition of this, each scientist profile included in the ranking underwent manual verification. This process involved cross-referencing publications and citation records across a wide spectrum of trustworthy academic sources to ensure accuracy and prevent erroneous attributions.
Although not directly influencing the final ranking position, the volume of publications in high-impact journals and renowned conference proceedings is considered a valuable secondary indicator of a scientist’s meaningful contributions to Immunology research. This complementary perspective supports the integrity and multidimensional evaluation of each profile.
The final positioning in the ranking is determined exclusively based on each researcher’s D-index, as derived from OpenAlex and CrossRef data—the two most well-regarded bibliometric databases available.
