A researcher’s position within the ranking is determined by their D-index (Discipline H-index), a refined variant of the traditional H-index that exclusively accounts for publications and citations within the researcher’s examined discipline. This approach provides a granular and discipline-specific measure of scientific contribution, allowing for meaningful comparisons amongst peers active in Engineering and Technology.
Scope of Research and Qualification Criteria
To establish the ranking, a total of 279,971 scientist profiles were examined from a wide array of bibliometric sources covering all scientific disciplines. Among these, 10,000 scientists were identified as operating specifically within the domain of Engineering and Technology. Inclusion in the ranking required that a scientist’s D-index be at least 30, with a majority of their tier publications concentrated in Engineering and Technology. Additionally, consideration was given to scientists’ notable awards and achievements within this field.
The threshold for the D-index required to be considered among top researchers is dynamically set as increments of 10, scaled relative to the estimated total number of scholars in each discipline. This methodology ensures representation of the top 1% of leading experts. Furthermore, to guarantee disciplinary focus and relevance, a scientist’s D-index must be within 30% or less of their general H-index, thus maintaining proximity between overall impact and discipline-specific performance.
Verification and Validation Practices
The team behind this ranking recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or influence. To safeguard accuracy and credibility, every scientist profile included was carefully and manually verified. Cross-correlation was performed against publications listed in a variety of trusted and established sources to confirm affiliations and research output.
While not directly influencing the D-index or final ranking position, the number of papers published in prominent journals and conference proceedings has been considered a valuable secondary signal indicating a scientist’s active and impactful contribution within Engineering and Technology research.
The final ranking position is based on each researcher’s D-index as computed from data gathered primarily from OpenAlex and CrossRef, the most prominent and widely recognized bibliometric databases accessible to the research community.
