An institution's position in the ranking is derived from the collective D-indexes (Discipline H-index) of all included scholars whose main publication area is Engineering and Technology. The D-index is a precise metric that considers only publications and citation data directly related to the specified discipline, ensuring relevancy and accuracy in the assessment.
Scope of Research Evaluated
A comprehensive examination was performed with 279,971 scientist profiles identified across diverse bibliometric data sources to ensure a robust and representative assessment. From this pool, 50,429 scientists specializing in Engineering and Technology were further analyzed.
For inclusion in the analysis, a scientist had to meet a D-index threshold of 30, with a majority of their noteworthy publications classified within Engineering and Technology. In addition to citation metrics, each researcher’s awards and notable achievements within their field were also taken into consideration.
The D-index threshold for identifying top researchers increases in increments of 10 according to the total number of scholars estimated for each discipline, while ensuring the integration of the top 1% of leading scholars into the final listing. To maintain subject fidelity, the divergence between a scientist’s general H-index and their D-index must not exceed 30%. Furthermore, recognition of scientists’ awards and distinguished accomplishments in their respective fields supplements the metric criteria.
Verification and Validation Practices
The team behind the Research.com ranking understands that raw bibliometric data alone does not suffice for a nuanced evaluation of scholarly output. Consequently, all scientist profiles were subject to thorough manual verification and cross-referenced against publications documented in a broad spectrum of trusted sources.
While the sheer quantity of research articles published in leading journals and conference proceedings is not a direct factor influencing placement in the Research.com ranking, it remains a valuable supplementary indicator of a scientist’s research contributions. The ranking positions are assigned based on H-index values aggregated from OpenAlex and CrossRef—recognized as the most comprehensive bibliometric platforms accessible to the research ecosystem.
