The bibliometric data used to devise the citation-based metrics for this ranking were collected on January 12, 2026. This allowed for the assembly of up-to-date, accurate citation counts and publication details, ensuring that the researcher evaluations reflect the current state of scientific contributions within the field.
A researcher’s position in this ranking is determined by their D-index (Discipline H-index), which specifically accounts for publications and citations strictly within the examined discipline of Engineering and Technology. This discipline-focused metric allows for a nuanced evaluation that reflects a scientist’s impact in their specialized area, rather than across a broader or unrelated set of fields.
Scope of Research and Eligibility Criteria
The ranking comprehensively examined 279,971 scientist profiles identified through diverse bibliometric data sources across all disciplines. Within this broad corpus, 56 scientists specializing in the field of Engineering and Technology were specifically analyzed. To qualify for inclusion in the ranking, a scientist’s D-index was required to be at least 30. Furthermore, a majority of their tier publications had to be categorized explicitly within the Engineering and Technology domain.
In addition to D-index criteria, scientists’ awards and achievements in the Engineering and Technology field were also evaluated as supplementary factors contributing to the final ranking. The threshold for the D-index varies incrementally by 10 points relative to the estimated total number of active scholars in each discipline, ensuring the inclusion of the top 1% of leading experts. Another important inclusion criterion is that the proximity between a scientist’s general H-index and their D-index must be 30% or less. This ensures that the researcher’s impact is both significant and concentrated within their primary discipline.
Verification and Validation Procedures
Recognizing that raw bibliometric data alone cannot definitively measure a researcher’s full output or scientific impact, the Research.com team implemented stringent verification processes. Each scientist profile was manually reviewed and cross-correlated against multiple trustworthy publication sources. This approach mitigates errors related to data completeness, disambiguation of author identities, and inconsistencies in metadata.
While the position within the ranking is driven solely by the D-index calculated from OpenAlex and CrossRef data, the number of papers published in prominent journals and conference proceedings was also considered as a valuable secondary signal. This additional perspective provides nuanced insight into a scientist’s contribution and visibility within the Engineering and Technology research community.
The underlying bibliometric data and resulting D-index values were drawn from OpenAlex and CrossRef — the most prominent, credible, and community-endorsed databases for scientific publication and citation data available globally.
