Data Sources and Ranking Methodology
The 5th edition of the Research.com Best Engineering and Technology Scientists in United Arab Emirates Ranking relies primarily on comprehensive bibliometric data collected from OpenAlex and CrossRef, in addition to multiple other reputable bibliometric sources. The citation-based metrics used in this ranking were derived from data gathered on January 12, 2026. Each scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the publications and corresponding citation metrics relevant to the specific discipline under examination.
Scope of Research and Inclusion Criteria
This ranking is based on the analysis of 279,971 scientist profiles identified across a wide variety of bibliometric datasets covering all scientific disciplines. From this broad base, 31 scientists specializing in Engineering and Technology within the United Arab Emirates were specifically examined. To qualify for inclusion in the ranking, a scientist’s D-index had to meet a minimum threshold of 30, with a majority of their tier publications originating from the Engineering and Technology discipline. Additionally, scientists’ awards and achievements within this field were also considered as important factors.
The threshold for the D-index is calibrated in increments of 10, adjusted according to the estimated population size of scholars in each discipline. This calibration ensures that the top 1% of leading scholars in each field are represented. Furthermore, to ensure the discipline-specific relevance of a researcher, the proximity between their overall H-index and D-index had to be within 30% or less, reinforcing the focused nature of their expertise in Engineering and Technology.
Verification and Validation Practices
Understanding the limitations of raw bibliometric data, the research team behind this ranking conducted rigorous manual verification of all scientist profiles. These profiles were cross-correlated against publications indexed in an extensive range of trustworthy sources to confirm accuracy and scholarly impact. Although the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of their substantive contributions to their field.
The primary metric determining the ranking is the researcher’s D-index, which is computed based on information from OpenAlex and CrossRef — the two most prominent and widely respected bibliometric databases accessible to the global research community.
