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 papers and citations exclusively within the examined discipline—in this case, Engineering and Technology. This specialized approach ensures the ranking accurately represents a researcher’s impact in their respective field.
Scope of Research and Ranking Criteria
The ranking draws from a broad spectrum of scientific domains, having examined 279,971 scientist profiles identified from a variety of bibliometric data sources across all disciplines. Specifically, 7,000 scientists within the Engineering and Technology discipline were included for detailed evaluation.
To qualify for the ranking, a scientist must have a D-index of at least 30, with the majority of their tier publications situated firmly within the domain of Engineering and Technology. Additionally, awards and notable achievements in this field were considered as supplementary criteria to acknowledge distinguished contributions.
The D-index threshold for identifying top researchers is dynamically set, increasing in increments of 10 relative to the estimated total number of scholars in each discipline. This approach guarantees inclusion of the top 1% of leading scholars. Furthermore, to ensure disciplinary relevance, scientists included exhibit a proximity of 30% or less between their overall H-index and their D-index, confirming their significant research focus within Engineering and Technology.
Verification Practices and Methodology Transparency
The Research.com team recognizes that raw bibliometric data, while invaluable, is not an absolute instrument for evaluating scholarly output. Therefore, all scientist profiles incorporated into the ranking underwent meticulous manual verification and were cross-correlated against publications indexed in a wide array of trustworthy sources. This additional layer of scrutiny safeguards the accuracy and integrity of the ranking.
Although not a direct factor influencing a researcher’s position in the ranking, the number of publications in prominent journals and conference proceedings serves as a valuable secondary signal of a scientist’s scholarly contribution within their field.
Ultimately, the ranking position is established based on each researcher’s D-index as derived from data aggregated through OpenAlex and CrossRef—two of the most prominent and widely respected bibliometric databases available to the research community.
