Best Immunology Scientists 2026 in Portugal

A researcher’s position within the ranking is determined exclusively by their D-index (Discipline H-index). This metric refines the traditional H-index by focusing solely on papers and citation counts within the specified discipline—in this case, Immunology—thereby ensuring that the evaluation accurately reflects a scientist’s impact in the relevant field.

Scope of Research and Inclusion Criteria

A total of 187,135 scientist profiles across various disciplines were examined to develop this ranking, with 8 researchers specifically identified within Immunology. To be included in the ranking, scientists were required to have a minimum D-index of 40, ensuring the list profiles only those with substantial research impact. Additionally, the majority of their tier publications had to be within the field of Immunology, guaranteeing discipline-specific relevance.

In assessing candidates, accomplishments such as awards and notable achievements within Immunology were also taken into account to supplement metrics-based evaluation.

The D-index threshold for consideration is fine-tuned as an increment of 10, commensurate with the estimated total number of scholars in each discipline. This approach guarantees that the top 1% of leading scholars are incorporated into the list while maintaining consistent standards across fields. Furthermore, only candidates whose general H-index and D-index values differ by 30% or less were considered, ensuring alignment between their overall research influence and disciplinary focus.

Verification Practices and Methodology Transparency

Recognizing that bibliometric data alone cannot capture the full scope of a researcher’s contributions, all scientist profiles included in the ranking underwent manual verification and cross-correlation against publications listed in a wide array of trustworthy sources. This meticulous validation process guarantees that the profiles accurately represent the researchers’ scientific outputs and maintain the integrity of the ranking.

While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it serves as a valuable secondary indicator of their contributions within Immunology. The ranking itself is based on the D-index derived from data aggregated through OpenAlex and CrossRef, platforms widely acknowledged as the leading bibliometric databases accessible to the research community.
