All bibliometric data utilized to calculate relevant citation indicators were collected on January 12, 2026. A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a specialized metric that considers only the papers and citation data within the examined discipline—in this case, Engineering and Technology—thus ensuring a focused and relevant assessment of disciplinary impact.
Scope of Research and Ranking Criteria
Our ranking methodology began with an extensive dataset comprising 279,971 scientist profiles identified from a variety of bibliometric sources across all disciplines. Out of this broad spectrum, 2,184 scientists specializing in Engineering and Technology were specifically examined to create the discipline-focused ranking.
To qualify for inclusion, a researcher’s D-index must be at least 30, ensuring a baseline of significant scholarly impact within Engineering and Technology. Additionally, the majority of a scientist’s tier publications must pertain directly to this discipline. Recognizing the multifaceted nature of scholarly excellence, we also considered notable awards and achievements related to Engineering and Technology.
The threshold for the D-index is dynamically adjusted in increments of 10 based on the estimated total number of active scholars in each discipline. This adaptive approach guarantees that the ranking includes the top 1% of leading scholars per discipline. Furthermore, a proximity criterion is applied such that the difference between a researcher’s general H-index and their D-index does not exceed 30%, ensuring the ranking reflects a meaningful disciplinary focus.
Verification Practices and Methodological Integrity
We acknowledge that raw bibliometric data alone cannot fully encapsulate a scholar’s research contributions. Therefore, each scientist profile featured in the ranking underwent meticulous manual verification and was cross-referenced against publications indexed in a wide range of trustworthy sources. This rigorous vetting process helps to enhance the accuracy and authenticity of our results.
While the volume of publications in prominent journals and conference proceedings is not a direct factor influencing rank position, it provides a valuable secondary signal of a scientist’s influence and productivity within Engineering and Technology.
The final ranking positions are assigned based on each researcher’s D-index derived from data obtained from OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases accessible to the global research community.
