The ranking positions of scientists are determined based on their D-index (Discipline H-index), which is a refined bibliometric indicator considering only papers and citation metrics relevant to the specific discipline of Engineering and Technology. This specialization ensures that the ranking reflects a researcher’s impact within the targeted field rather than their general academic output.
Scope and Inclusion Criteria
In total, 279,971 scientist profiles spanning all disciplines were examined from a diverse range of bibliometric data sources. Specifically, 2,000 scientists within the Engineering and Technology disciplines were analyzed in detail. To qualify for inclusion in this ranking, a scientist must have a D-index of at least 30 and a majority of their tier publications concentrated in the Engineering and Technology area. Additionally, the evaluation took into account recognized awards and achievements pertinent to this field.
The threshold for considering top researchers’ D-index is carefully calibrated in increments of 10 based on the estimated population size of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading researchers, maintaining consistency and rigor across disciplines. Furthermore, to preserve focus and relevance, the D-index must be within 30% or less of a scientist’s overall general H-index, thus confirming their primary engagement in Engineering and Technology research.
Verification and Validation Practices
The team behind this ranking conducts meticulous verification to guarantee accuracy and credibility. Recognizing that raw bibliometric data cannot serve as an absolute measure of academic output, all scientist profiles were manually verified. This involved cross-correlating data against publications listed in a broad spectrum of trustworthy and reputable sources to confirm identity and disciplinary focus.
While not directly contributing to ranking positions, the number of papers published in prominent journals and reputable conference proceedings is considered a useful secondary indicator of a scientist’s contribution to the field. Importantly, the ranking position itself is determined solely by the D-index derived from data gathered via OpenAlex and CrossRef — the most prominent and reliable bibliometric databases accessible to the research community today.
