A researcher's position in the ranking is determined by their D-index (Discipline H-index), a metric that isolates papers and citation counts specifically within the examined discipline. This approach ensures that the evaluation reflects a scientist's impact within Engineering and Technology, rather than across unrelated fields.
Scope of Research Considered
The ranking was constructed from an extensive examination of 279,971 scientist profiles drawn from a variety of bibliometric data sources covering all disciplines. Of these, 393 scientists specializing in Engineering and Technology were thoroughly analyzed.
To qualify for inclusion in this ranking, a scientist's D-index had to meet or exceed a threshold of 30, and a majority of their tier publications were required to be within the domain of Engineering and Technology. In addition, notable awards and significant achievements in the field were considered as supplementary factors.
The D-index threshold for top researchers is established in increments of 10, calibrated according to the estimated population of scholars within each discipline. This ensures the selection consistently includes the top 1% of leading experts. Furthermore, there is a stringent criterion that the proximity between a scientist’s overall H-index and their D-index remains within 30%, guaranteeing discipline-specific relevance and impact.
Verification and Validation Processes
Recognizing that raw bibliometric data alone cannot fully reflect scholarly contributions, the team behind this ranking implemented meticulous manual verification practices. All scientist profiles were thoroughly cross-referenced against publications indexed in a wide array of reputable and trustworthy sources to confirm accuracy and authenticity.
While not directly influencing a researcher’s rank in the Research.com list, the total number of publications in prominent journals and conference proceedings was considered an important secondary indicator of a scientist’s influence within Engineering and Technology.
The final positions within the ranking are determined by D-index values derived from OpenAlex and CrossRef data. These databases represent the most extensive and reliable bibliometric repositories accessible to the scientific community.
