A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a discipline-specific adaptation of the H-index. The D-index exclusively considers papers and citation metrics relevant to the examined discipline, thereby providing a focused and meaningful evaluation of research impact within Engineering and Technology.
Scope of Research and Qualification Criteria
The ranking comprehensively examines 279,971 scientist profiles identified from a wide array of bibliometric data sources across all academic disciplines, including specifically 7,000 scientists associated with Engineering and Technology. To qualify for inclusion in the Engineering and Technology ranking, a scientist must have a D-index of at least 30. Furthermore, a majority of their tier publications—those considered of highest impact—must be situated within the Engineering and Technology domain.
In addition to quantitative bibliometric thresholds, qualitative factors such as awards and other notable achievements in Engineering and Technology have been incorporated into the assessment to better capture a scientist’s contributions and standing in the field. The D-index threshold for identifying top researchers within disciplines is dynamically set as increments of 10, proportional to the estimated total number of scholars in each discipline, while ensuring inclusion of the top 1% leading scholars. Careful attention is also given to confirming that there is a proximity of 30% or less between a scientist’s general H-index and their D-index, which mitigates discrepancies between their overall and discipline-specific impact.
Verification and Validation Practices
Recognizing that raw data or bibliometrics alone cannot serve as an absolute measure of scientific output and quality, the Research.com team conducts rigorous manual verification of scientist profiles. This includes cross-correlation of publication records against a wide range of trustworthy sources, ensuring the accuracy and relevancy of each profile represented in the ranking.
While the quantity of papers published in prestigious journals and conference proceedings is not a direct criterion influencing rank position, it remains an important secondary signal of a researcher’s contribution and influence within their scientific specialization.
The ranking positions are ultimately established using each researcher’s D-index based on information extracted from OpenAlex and CrossRef — the most prominent and respected bibliometric databases currently available to the global research community. We welcome readers to explore further details of our methodology on our methodology page.
