Institutions' positions in the ranking are determined by the sum of D-indexes (Discipline H-index) of all ranked scholars affiliated with each university, provided their primary publication area is Immunology. The D-index is an exclusive metric that incorporates only publications and citation data specific to Immunology, ensuring an accurate and discipline-focused assessment.
Scope of Research and Inclusion Criteria
The ranking encompasses an extensive evaluation of 279,971 scientist profiles sourced from a broad spectrum of bibliometric databases. Within this pool, 14,292 scientists specializing in Immunology were closely analyzed. To qualify for inclusion, a scholar must have a D-index of at least 40, with the majority of their top-tier publications in Immunology.
In addition to bibliometric data, the ranking also considers a scientist’s awards and achievements in the field of Immunology. The D-index threshold for identifying top researchers is set in increments of 10, calibrated to align with the number of scholars in each discipline, while guaranteeing that the top 1% of leading scholars are included. Moreover, a scientist's general H-index should not exceed their D-index by more than 30%, thereby ensuring a close proximity between general and discipline-specific impact.
Awards and career accomplishments are further considered to highlight those researchers whose contributions have been recognized by the academic and professional community.
Verification and Validation Practices
The Research.com team recognizes that quantitative metrics alone do not provide a complete picture of scholarly impact. All scientist profiles underwent manual verification and were systematically cross-validated against publications in a wide array of reputable sources. Though the number of papers published in leading journals and conference proceedings is not a factor in the final ranking position, it is acknowledged as a valuable secondary indicator of a scholar's research contribution.
Ranking positions are established using each researcher’s H-index derived from up-to-date data obtained from OpenAlex and CrossRef, the most reliable and widely recognized bibliometric databases in the academic community.
