All bibliometric data used to devise the citation-based metrics underpinning the ranking were collected on January 12, 2026. The position of each scientist within the ranking is determined by their D-index (Discipline H-index), a specialized metric that incorporates only a researcher's publications and citation records within the discipline under evaluation—in this case, Engineering and Technology. This discipline-specific approach ensures a more precise reflection of expertise and impact within the targeted research area.
Scope of Research and Eligibility Criteria
The ranking process commenced with a thorough examination of 279,971 scientist profiles aggregated from a wide array of bibliometric databases and sources, spanning all scientific disciplines. From this extensive pool, 31 scientists specializing in Engineering and Technology within the United Arab Emirates were selected for detailed evaluation.
To qualify for inclusion, scientists were required to meet a minimum D-index threshold of 30, ensuring that only researchers demonstrating substantial discipline-focused scholarly impact were considered. Furthermore, a majority of the candidate’s tier publications needed to be situated squarely within the domain of Engineering and Technology. Recognition of significant awards and achievements in the field also contributed to the evaluation process, reinforcing the identification of leading experts.
The D-index threshold was calibrated dynamically, increasing in increments of 10 relative to the estimated total number of scholars within each specific discipline. This approach was carefully designed to consistently include the top 1% of leading scholars. Additionally, a proximity constraint was applied to confirm alignment between each scientist's general H-index and their D-index, stipulating that the difference between these two indices should not exceed 30%. This ensures that recognized researchers maintain a strong and focused contribution within the examined discipline.
Verification and Validation Procedures
Research.com’s team recognizes that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s contributions. Accordingly, all scientist profiles included in the ranking underwent rigorous manual verification. This process involved cross-correlating publication records against an extensive range of credible sources to confirm accuracy and authenticity.
While not directly influencing a researcher's position in the ranking, the quantity of papers published in prominent journals and conference proceedings provides a valuable secondary indicator of impact, emphasizing the breadth and visibility of each scientist’s contributions to Engineering and Technology research.
The determination of ranking positions is ultimately grounded in the D-index, constructed from expertly gathered data within OpenAlex and CrossRef, widely recognized as the most comprehensive and trustworthy bibliometric databases of their kind.
