A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric that accounts exclusively for papers and citation counts within the specific discipline under examination, here being Engineering and Technology. This approach ensures a focused evaluation of a researcher’s impact and productivity in their primary field.
Scope of Research
This ranking comprehensively examined 279,971 scientist profiles identified across a broad array of bibliometric data sources covering all scientific disciplines. From this extensive pool, 24 scientists specializing specifically in Engineering and Technology were evaluated in detail.
To qualify for inclusion, a scientist’s D-index had to be at least 30, indicating a significant and sustained impact within the discipline. Furthermore, a majority of the researcher’s tier publications needed to be categorized within the field of Engineering and Technology. Consideration was also given to scientists’ notable awards and achievements relevant to this domain.
The threshold D-index for top researchers is escalated in increments of 10 depending on the estimated total number of scholars within each discipline, while simultaneously ensuring that the top 1% of leading scientists are incorporated into the ranking. Additionally, a proximity criterion requires the difference between a scientist’s general H-index and their D-index to be 30% or less, supporting consistency between overall and discipline-specific impact.
Additional Verification Practices
The Research.com team recognizes that raw bibliometric data alone cannot fully capture the output and influence of scholars. Therefore, all scientist profiles included in the ranking underwent rigorous manual verification. This process involved cross-correlating profiles against publications documented in a wide range of trustworthy sources to ensure accuracy and integrity.
While not directly determining the ranking placement, the number of papers published in prominent journals and conference proceedings is regarded as a valuable secondary indicator of a scientist’s contribution to the field. By emphasizing both quantitative metrics and qualitative verification, we strive to present a credible and well-rounded evaluation.
As noted, the position in the ranking is fundamentally established using each researcher’s D-index, derived from data aggregated from OpenAlex and CrossRef. These databases represent the most comprehensive and frequently updated sources available, reinforcing the credibility of the ranking outcomes.
