Data Sources and Bibliometric Information
The 5th edition of the Research.com Best Immunology Scientists in Italy Ranking is primarily based on comprehensive data compiled from OpenAlex and CrossRef, alongside multiple other reputable bibliometric data sources. To ensure accuracy and currency, all citation-based metrics utilized to determine the ranking positions were collected on January 12, 2026. A key metric employed in the ranking is the D-index (Discipline H-index), a specialized adaptation of the traditional H-index that only accounts for a researcher's publications and citations within the specified discipline of Immunology. This approach enables a focused and discipline-specific evaluation of scientific impact.
Scope of Research and Eligibility Criteria
In developing the ranking, an extensive examination was conducted on a pool of 187,135 scientist profiles drawn from a multitude of bibliometric databases spanning all scientific disciplines. Of these, 219 scientists were identified as active contributors within the field of Immunology. To qualify for inclusion in this ranking, a scientist was required to have a D-index of at least 40, ensuring a minimum threshold of sustained research performance within Immunology. Additionally, the majority of a qualifying scientist’s tier publications needed to be concentrated in Immunology to confirm their discipline specificity. Awards and notable achievements in the field of Immunology were also factored into the vetting process.
The D-index threshold for identifying top researchers is calibrated as increments of 10 depending on the estimated total number of scholars within each discipline, thereby guaranteeing representation of approximately the top 1% of leading experts. Furthermore, a proximity criterion was applied such that the difference between a scientist’s general H-index and their Immunology-specific D-index did not exceed 30%, ensuring that their overall research excellence aligns closely with their impact within Immunology.
Verification and Validation Practices
At Research.com, we recognize that raw bibliometric data cannot serve as an absolute measure of scholarly output or impact. Accordingly, all scientist profiles included in the ranking underwent rigorous manual verification. This process involved cross-correlating publication records against a broad spectrum of trustworthy sources, ensuring the authenticity and relevance of the data. While the number of papers published in high-impact journals and conference proceedings does not directly influence the numerical ranking position, such publication metrics are regarded as valuable secondary indicators of a scientist’s contribution to the Immunology research community.
The position of each scientist in the ranking is ultimately established through the analysis of their D-index, derived from the bibliometric information curated by OpenAlex and CrossRef—two of the most prominent and widely acknowledged databases available to the global research community.
