Data Sources and Bibliometric Metrics
The 5th edition of the Research.com Best Immunology Scientists in Romania Ranking has been developed using a comprehensive array of bibliometric data primarily sourced from OpenAlex and CrossRef, alongside multiple other reputable data repositories. These sources provide extensive coverage of scholarly publications and citation metrics across disciplines, enabling a robust evaluation framework. The bibliometric data underpinning the citation-based metrics incorporated into this ranking were collected on January 12, 2026. Each scientist’s position within the ranking is determined by their Discipline H-index, or D-index, a metric specifically tailored to consider only those publications and citations pertinent to the field under examination—in this case, Immunology.
Scope of Research and Inclusion Criteria
An extensive dataset encompassing 187,135 scientist profiles identified from a diverse range of bibliometric sources was analyzed across all disciplines. Within this dataset, 1,425 scientists specializing in Immunology were specifically examined. To qualify for inclusion in the Immunology ranking, a scientist’s D-index was required to be at least 40, and a majority of their tier publications had to be within the domain of Immunology. Additionally, recognition in the form of awards and notable achievements in Immunology was taken into account as supplementary evidence of research excellence.
The threshold for the D-index is calibrated in increments of 10 according to the estimated total number of active scholars in each discipline, a system designed to ensure that the top 1% of leading researchers are consistently represented. Furthermore, to maintain disciplinary relevance, the discrepancy between a scientist’s general H-index and their D-index was constrained to a proximity of no more than 30%.
Verification Practices and Ranking Methodology
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the team behind this ranking has instituted rigorous verification procedures. All scientist profiles were manually vetted and cross-referenced against publications indexed in a broad spectrum of trusted academic sources, ensuring accuracy and authenticity of the data.
While not influencing the formal ranking position, the number of papers published in leading journals and at prestigious conferences is nonetheless regarded as a valuable secondary indicator of a scientist’s impact within their field. The overall ranking position relies primarily on each researcher’s D-index as derived from OpenAlex and CrossRef—the two foremost and widely recognized bibliometric repositories accessible to the global research community.
