A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and corresponding citation data relevant to the specified discipline, in this case, Engineering and Technology. This discipline-focused approach enables a more precise and meaningful evaluation of each researcher’s impact within their primary field of expertise.
Scope of Research and Eligibility Criteria
The ranking process examined a total of 279,971 scientist profiles derived from an extensive array of bibliometric data sources across all disciplines. Within this dataset, 389 scientists specifically affiliated with Engineering and Technology were rigorously analyzed. To qualify for inclusion in the ranking, a scientist’s D-index had to be at least 30, reflecting a significant level of scholarly influence within the discipline. Furthermore, a majority of the scientist’s tier publications needed to be anchored in Engineering and Technology, ensuring domain specificity.
In addition to bibliometric indicators, scientists’ awards and recognized achievements within the field of Engineering and Technology were also factored into the evaluation. The D-index threshold is dynamically adjusted in increments of 10 according to the estimated total number of scholars in each discipline, while guaranteeing that the top 1% of leading experts are systematically incorporated.
To maintain rigorous discipline specificity, the ranking requires that the disparity between a scientist’s general H-index and their D-index remains at 30% or less. This criterion safeguards against disproportionate influence from publications outside the focal research domain.
Additional Verification Practices
Understanding the inherent limitations of raw bibliometric data as an absolute measure, the Research.com team has engaged in thorough manual verification of all scientist profiles. These verifications include cross-correlation with publications listed in a broad range of trustworthy and validated scholarly sources.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a scientist’s active and sustained contribution to the specific area of research.
The final ranking positions are established exclusively by analyzing each researcher’s D-index, derived from data gathered via OpenAlex and CrossRef. These platforms are widely recognized as the leading and most reliable bibliometric databases available.
