A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that considers only those publications and associated citation metrics specifically within the discipline under examination—in this case, Engineering and Technology. This focus ensures that the ranking reflects disciplinary expertise rather than overall research output.
Scope of Research and Qualification Criteria
This ranking rigorously examined a total of 279,971 scientist profiles spanning a broad spectrum of disciplines, with 2,794 profiles identified within the domain of Engineering and Technology. To qualify for inclusion, a scientist must have a D-index of at least 30, with the majority of their tier publications concentrated in the Engineering and Technology field.
In addition to bibliometric thresholds, a scientist’s awards and achievements relevant to Engineering and Technology were incorporated as qualitative factors to further validate their standing in the discipline. The D-index threshold for top researchers is dynamically set as increments of 10, calibrated to the estimated size of the scholarly community within each discipline, thereby ensuring that approximately the top 1% of leading scholars in the field are included.
Moreover, to maintain rigorous disciplinary alignment, profiles were filtered to include only those with a D-index that deviates by no more than 30% from their general H-index, ensuring close proximity between overall and discipline-specific impact.
Verification and Validation Practices
Recognizing the inherent limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team implemented thorough manual verification of all scientist profiles. Each profile was cross-correlated with publications verified through a wide array of authoritative and trustworthy sources to enhance accuracy and reliability.
Although the quantity of papers published in prominent journals and conference proceedings does not directly influence position in the ranking, it serves as a valuable secondary signal that complements citation-based metrics to reflect a scientist’s contributions within their research area.
The final ranking positions are established exclusively using each researcher’s D-index derived from OpenAlex and CrossRef, the preeminent bibliometric databases recognized by the global research community for their rigor and comprehensiveness.
