A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that focuses exclusively on publications and citations pertinent to the examined discipline—in this case, Engineering and Technology. This approach allows for a more precise evaluation of a researcher’s impact within their specific field.
Scope of Research and Inclusion Criteria
The underlying data pool comprised 279,971 scientist profiles identified across a wide array of bibliometric sources spanning all academic disciplines. Specifically, 2,892 scientists from the Engineering and Technology fields were analyzed in detail. To qualify for inclusion in the ranking, candidates were required to have a D-index of at least 30, with the majority of their tier publications originating within the Engineering and Technology domain.
Beyond bibliometric thresholds, scientists’ professional awards and achievements within the Engineering and Technology sector were also taken into account as part of a holistic evaluation process. The D-index cutoff for top researchers is dynamically adjusted in increments of 10 depending on the estimated scholar population in each discipline. This criterion is designed to guarantee the inclusion of the top 1% of leading scholars.
Moreover, to ensure the relevance and focus of the ranking, there is an enforced proximity constraint where the difference between a scientist’s general H-index and their D-index must be 30% or less, further validating that the disciplinary impact is reflective of the researcher’s core expertise.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the Research.com team implemented rigorous manual verification processes. Every scientist profile considered in the ranking was carefully checked and cross-correlated against publications registered in numerous trustworthy academic sources and databases.
While the quantity of papers published in high-impact journals and prestigious conference proceedings is not a direct factor affecting the ranking position, it serves as a valuable secondary signal of a scientist’s contribution to their field.
The final positioning in the ranking is exclusively driven by each researcher’s D-index as derived from OpenAlex and CrossRef, which are widely regarded as the most comprehensive and authoritative bibliometric databases available to the scholarly community.
