Data Sources and Ranking Metrics
The 5th edition of the Research.com Best Molecular Biology Scientists in Iran Ranking is primarily constructed using comprehensive bibliometric data sourced from OpenAlex and CrossRef, supplemented by multiple other reputable data repositories. The citation-based metrics underlying this ranking were collected on January 12, 2026, ensuring currency and relevance in the evaluation process. Each scientist's position within the ranking is determined by their Discipline H-index, commonly referred to as the D-index. This metric specifically accounts for a researcher’s publications and citations strictly within the examined discipline of Molecular Biology, providing a focused measure of scholarly impact in the field.
Scope and Criteria of Research
The ranking examined a total of 187,969 scientist profiles gathered from an array of bibliometric databases spanning all scientific disciplines. Within this extensive dataset, 5 scientists specialized in Molecular Biology were identified and analyzed to formulate this specific ranking. To qualify for inclusion, a scientist was required to have a D-index of at least 40, with a majority of their tier publications concentrated in Molecular Biology. Additionally, notable awards and achievements relevant to this discipline were considered as supplementary factors in the assessment.
The D-index threshold for recognizing top researchers is dynamically set, increasing in increments of 10 according to the overall estimated population of scholars within each discipline. This method guarantees that the top 1% of leading scholars per field are incorporated in the ranking. Furthermore, to ensure a consistent disciplinary focus, a proximity criterion mandates that the gap between a scientist’s general H-index and their D-index remain at 30% or less.
Verification and Validation Practices
The team responsible for compiling this ranking acknowledges that raw bibliometric data alone cannot serve as an absolute or definitive evaluation tool for research output. Accordingly, all scientist profiles underwent meticulous manual verification. This process included cross-correlation of publication records against a broad spectrum of trustworthy academic sources to confirm accuracy and relevance.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s position within the Research.com ranking, it constitutes a valuable secondary signal of their contributions to the Molecular Biology field. The ranking position itself is strictly established through the D-index calculated from data obtained via OpenAlex and CrossRef—two of the most respected and widely recognized bibliometric databases available to the scholarly community.
