Bibliometric data utilized to devise the citation-based metrics were collected on January 12, 2026. The ranking methodology is centered on the D-index (Discipline H-index), a refined metric that quantifies a researcher's impact exclusively within the examined discipline. This approach ensures that only publications and citation metrics relevant to Engineering and Technology are considered when determining a scientist’s position in the ranking.
Scope of Research and Ranking Inclusion Criteria
The ranking evaluation comprehensively examined a total of 279,971 scientist profiles identified across a broad array of bibliometric data sources, spanning all research disciplines. Specifically, within Engineering and Technology, the study focused on 4,000 scientists whose contributions were critically assessed.
To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 30, reflecting a significant scholarly impact within the field. Furthermore, the majority of a qualifying scientist’s tier publications needed to be concentrated in Engineering and Technology, ensuring alignment with the discipline’s core areas. Additionally, awards and professional achievements pertinent to Engineering and Technology were incorporated as supplementary criteria to enhance the robustness of the evaluation.
The threshold for the D-index is dynamically adjusted by increments of 10, based on the estimated total number of scholars within each discipline. This adaptive mechanism guarantees that the ranking includes the top 1% of leading experts in the field. A critical requirement applied across all profiles is that the proximity between a scientist’s general H-index and their D-index should not exceed 30%, maintaining consistency between the overall and discipline-specific measures of impact.
Verification and Validation Practices
The researchers behind this ranking recognize that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or quality. Therefore, every scientist profile included was subjected to a thorough manual verification process. Profiles were cross-correlated against publications sourced from a wide range of trustworthy academic and scientific outlets to confirm accuracy and relevance.
Although not directly influencing the ranking position, the quantity of papers published in prominent journals and conference proceedings was evaluated as a valuable secondary indicator of a scientist’s contribution to their specific domain.
The final ranking position is established exclusively using each researcher’s D-index based on data gathered from OpenAlex and CrossRef, ensuring transparency and standardization in the evaluation process.
