A scientist's position within this ranking is determined by their D-index (Discipline H-index). Unlike a traditional H-index, the D-index focuses exclusively on publications and citations relevant to the specific discipline under examination—in this case, Engineering and Technology. This approach ensures that the ranking reflects a researcher's impact and influence specifically within their area of expertise.
Scope of Research and Qualification Criteria
For this edition, a thorough review of 279,971 scientist profiles across all scientific disciplines was conducted using a range of bibliometric data sources. From this extensive dataset, 115 scientists specifically engaged in Engineering and Technology were identified and evaluated.
To qualify for inclusion in the ranking, a researcher’s D-index in Engineering and Technology had to be at least 30, ensuring that only highly impactful scientists were considered. Additionally, the majority of a qualifying scientist’s tier publications needed to be classified within Engineering and Technology, reflecting a focused and substantial contribution to the field. Award recognitions and notable achievements within the discipline were also factored into the evaluation process.
The threshold for the D-index is tailored for each discipline, increasing in increments of 10 relative to the estimated total number of scholars active in that field. This methodology guarantees that the top 1% of leading researchers are incorporated into the ranking. Furthermore, a constraint was applied to maintain a proximity of 30% or less between a scientist’s general H-index and their D-index, ensuring consistency and relevance of disciplinary impact.
Verification and Methodological Integrity
Recognizing that raw bibliometric data alone can never provide an absolute measure of scholarly contribution, the team behind this ranking implemented rigorous manual verification procedures. All scientist profiles were carefully cross-checked against publications listed in a broad spectrum of trustworthy academic outlets to validate their accuracy and authenticity.
While the number of papers published in high-impact journals and conference proceedings does not directly influence a researcher’s ranking position, this metric serves as an important complementary indicator of a scientist’s engagement and influence in the field. The final ranking is decisively based on the D-index computed from OpenAlex and CrossRef data, ensuring reliance on the most comprehensive and accurate bibliometric information available to the research community.
