Data Sources and Citation Metrics
The 5th edition of the Research.com Best Genetics Scientists in Brazil Ranking is primarily based on comprehensive bibliometric data sourced from OpenAlex and CrossRef, alongside multiple other reputable academic databases. These platforms provide rich, up-to-date metadata on publications, citations, and author profiles across a wide spectrum of disciplines. The bibliometric data used to calculate the citation-based metrics underlying this ranking were collected on January 12, 2026.
A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a metric that refines the traditional H-index by isolating publications and citations specific to the Genetics discipline. This focused approach ensures that the evaluation reflects a researcher’s impact within their specialized field rather than their overall academic influence.
Scope and Criteria of the Ranking
For this edition, a total of 187,823 scientist profiles across all disciplines were examined, with 13 scientists identified specifically within Genetics based on the collective bibliometric data. To qualify for inclusion in the Genetics ranking, a scientist was required to have a D-index of at least 40, with the majority of their highest-impact publications being concentrated in the Genetics area. Additionally, notable awards and achievements relevant to Genetics were taken into account to further validate their expertise.
The threshold for the D-index is dynamically adjusted in increments of 10 to correspond with the estimated population size of top researchers within each discipline, ensuring that approximately the top 1% of leading scholars are consistently represented in the ranking. Furthermore, a proximity criterion was applied whereby a researcher’s general H-index and their Genetics D-index differ by no more than 30%, emphasizing discipline-specific influence rather than general academic breadth.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot capture the full scope of a researcher’s contributions, all scientist profiles underwent meticulous manual verification. This process involved cross-referencing publications with multiple trustworthy sources to validate accuracy and ensure the integrity of the data.
While the number of publications in prestigious journals and conference proceedings is not a factor influencing the ranking position, it remains a valuable secondary signal of a researcher’s contribution to their field.
The final ranking positions are determined exclusively by carefully curated D-index values derived from OpenAlex and CrossRef—the most prominent and widely respected bibliometric databases available to the research community.
