Data Sources and Citation Metrics
The 5th edition of the Research.com Best Genetics Scientists in Iceland Ranking relies primarily on comprehensive bibliometric data sourced from OpenAlex and CrossRef, supplemented by multiple additional reputable databases. The bibliometric data used to derive the citation-based metrics were collected on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only those publications and citation counts relevant to the specific discipline under examination—in this case, Genetics.
Scope of Research and Selection Criteria
Our evaluation encompassed 187,823 scientist profiles aggregated from a broad spectrum of bibliometric data sources across all disciplines. Specifically for Genetics, 20 scientists were identified and examined in depth. To qualify for inclusion in the ranking, a scientist must have achieved a minimum D-index of 40, with the majority of their tier publications concentrated in Genetics. Additionally, scientists’ awards and field-specific achievements were factored into the assessment.
The D-index threshold is dynamically adjusted in increments of 10 depending on the estimated total number of scholars within each discipline to ensure the inclusion of the top 1% of leading experts. To further guarantee disciplinary relevance, candidates are required to exhibit a proximity of 30% or less between their general H-index and their Genetics-specific D-index.
Verification Procedures and Methodological Rigor
We recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output. Therefore, all scientist profiles underwent meticulous manual verification and were cross-correlated against publications indexed in a broad array of trustworthy sources. While the number of publications in leading journals and conference proceedings does not directly inform the ranking position, it provides an important secondary signal of a researcher’s contribution to their field.
The ranking positions are established exclusively via each researcher’s D-index, computed from data obtained through OpenAlex and CrossRef—two of the most authoritative and widely used bibliometric databases within the research community.
