A scientist’s placement within this ranking is determined by their D-index (Discipline H-index), a discipline-specific metric that exclusively accounts for papers and citation metrics relevant to the examined field of Plant Science and Agronomy. This approach ensures that ranking positions accurately reflect a researcher’s specialized impact within their discipline, rather than broader, potentially less relevant metrics.
Scope of Research and Qualification Criteria
The ranking systematically examined a total of 279,971 scientist profiles compiled from a diverse array of bibliometric data sources spanning all scientific disciplines. Within this expansive dataset, 12 scientists specializing in Plant Science and Agronomy were specifically identified for inclusion.
To qualify for this ranking, a scientist was required to meet a minimum D-index threshold of 30, tailored to guarantee the inclusion of the top 1% of scholars within the discipline. This threshold is determined in increments of 10 relative to the estimated total number of scholars in each specific field. Moreover, a qualifying scientist’s majority of tier publications had to be concentrated in Plant Science and Agronomy, further ensuring topical relevance.
Additional consideration was given to scientists’ awards and notable achievements within the discipline, reinforcing the weighting of peer-recognized contributions. An important calibration factor ensured that the proximity between a scientist’s general H-index and their D-index did not exceed 30%, thereby confirming that researchers ranked demonstrate a focused disciplinary impact rather than a generalist citation footprint.
Verification and Validation Procedures
Understanding the limitations of raw bibliometric data as an absolute evaluative tool, the researchers behind this ranking undertook meticulous manual verification of all scientist profiles considered. Each profile was cross-correlated against publications tracked across a broad range of trustworthy and authoritative sources to confirm accuracy and mitigate errors such as author name ambiguity and publication misclassification.
While the number of publications in high-impact journals and prominent conference proceedings does not directly influence positioning in the Research.com ranking, it serves as a valuable secondary indicator of a scientist’s substantive contribution to research within Plant Science and Agronomy.
The final ranking positions were exclusively established using each researcher’s verified D-index, derived from data consolidated through OpenAlex and CrossRef.
