A scientist’s position within the ranking is determined by their Discipline H-index (D-index), a refined metric which accounts exclusively for publications and citations within the specific discipline under evaluation—in this case, Engineering and Technology. This approach ensures that the ranking reflects contributions and influence that are directly relevant to the field.
Scope of Research and Selection Criteria
The ranking is based on an extensive examination of 279,971 scientist profiles identified from diverse bibliometric data sources across all academic disciplines. Within the domain of Engineering and Technology, 8,000 scientists were carefully assessed. To qualify for inclusion in the ranking, researchers must meet the following criteria:
- Achieve a minimum D-index of 30 in Engineering and Technology.
- Have a majority of their tier publications situated within the area of Engineering and Technology.
- Demonstrate recognized awards and achievements specific to the Engineering and Technology field.
The D-index thresholds for ranking consideration are calibrated in increments of 10, relative to the estimated total number of active scholars for each discipline. This methodology is designed to guarantee representation of the top 1% of leading researchers in each specialized area. Furthermore, to ensure relevance and domain-specific focus, a researcher’s D-index must be within 30% of their general H-index.
Verification and Validation Procedures
At Research.com, we acknowledge that raw bibliometric data alone cannot fully capture the complexity and significance of a scholar’s work. Accordingly, each scientist’s profile in this ranking has undergone rigorous manual verification and cross-correlation against publications listed in a broad spectrum of trustworthy sources. This meticulous validation enhances the accuracy and reliability of the ranking.
Although it does not directly influence a researcher’s position within the ranking, the volume of papers published in prominent journals and conference proceedings is considered an important secondary signal of scientific contribution and impact within the discipline.
The definitive ranking positions are established using each researcher’s D-index as computed from information gathered primarily through OpenAlex and CrossRef. These are among the most prominent and widely recognized bibliometric databases accessible to the scholarly community globally.
