A scientist’s position within the ranking is strictly based on their D-index (Discipline H-index), a metric that evaluates research impact by considering only papers and citation metrics relevant to the examined discipline of Engineering and Technology. This approach ensures that the ranking accurately reflects a researcher’s domain-specific contributions rather than general citation performance across unrelated fields.
Scope of Research and Qualification Criteria
Our analysis encompassed a broad spectrum of 279,971 scientist profiles identified through various bibliometric data sources, covering all academic disciplines. Within these, 2,000 scientists specializing specifically in Engineering and Technology were examined in detail for this ranking.
To qualify for inclusion, a scientist’s D-index needed to be at least 30. Additionally, a majority of their tier publications had to be within Engineering and Technology, underscoring a strong disciplinary focus. Beyond bibliometric measures, awards and achievements in the field were also carefully considered as supplementary factors, reflecting recognition by peers and the wider scientific community.
The threshold for the D-index varies incrementally by 10 points depending on the estimated total number of scholars per discipline, ensuring that the selection consistently incorporates the top 1% of leading experts. Furthermore, the difference between a scientist’s general H-index and their D-index was required to be 30% or less, guaranteeing that the discipline-specific impact is commensurate with overall research influence.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of research quality, we implemented extensive manual verification protocols. Each scientist’s profile was carefully reviewed, cross-correlated against publications from a wide array of trustworthy sources, including prominent journals and conference proceedings, to affirm authorship and disciplinary relevance.
While the number of publications in prestigious outlets does not directly influence a researcher’s ranking position, it constitutes an important secondary indicator of scholarly contribution and research excellence within Engineering and Technology.
Ultimately, the ranking position is firmly established on the D-index calculated from robust data obtained through OpenAlex and CrossRef — two of the most respected and widely used bibliometric platforms available to the scientific community.
