A scientist's position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that quantifies a researcher's impact within a specific discipline. Unlike the general H-index, the D-index exclusively considers publications and citations relevant to the discipline under examination—in this case, Engineering and Technology—thereby ensuring a precise reflection of disciplinary research influence.
Scope of Research and Qualification Criteria
To construct this ranking, a total of 279,971 scientist profiles identified from diverse bibliometric data sources across all disciplines were analyzed. Within this extensive dataset, 55 scientists specializing in Engineering and Technology were evaluated in detail.
To qualify for inclusion in the ranking, each scientist was required to have a D-index of at least 30, with the majority of their tier publications situated within the field of Engineering and Technology. Additionally, recognition of awards and other notable achievements in the domain were factored into the assessment process.
The threshold for the D-index is dynamically calibrated in increments of 10 based on the estimated total number of scholars per discipline, thereby ensuring representation of the top 1% of leading researchers within each field. Furthermore, to maintain consistency and disciplinary relevance, a proximity of no more than 30% between a researcher’s general H-index and their D-index is mandated.
Verification and Validation Practices
Aware that raw bibliometric data cannot serve as an absolute measure of scholarly output or merit, our research team undertook extensive manual verification of all scientist profiles. Each profile was meticulously cross-correlated against publications curated from a broad array of reputable sources to confirm accuracy and comprehensiveness.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it provides a valuable secondary signal of the scientist’s contribution within their specific area of study.
The final ranking positions are established through the D-index calculated using bibliometric information extracted from OpenAlex and CrossRef, which stand as the most prominent and recognized citation databases available today.
