A scientist’s position in the ranking is determined by their D-index (Discipline H-index), which specifically accounts for papers and citation metrics within the targeted discipline of Engineering and Technology. This focus ensures that the ranking accurately reflects a researcher’s disciplinary impact rather than general citation profiles.
Scope of Research and Qualification Criteria
In forming this ranking, a total of 279,971 scientist profiles identified from various bibliometric sources were examined across all academic disciplines. Within this extensive pool, 1,001 scientists specializing in Engineering and Technology were specifically evaluated for inclusion.
To qualify for the ranking, each scientist was required to meet the following criteria:
- Possess a minimum D-index of 30 within the Engineering and Technology discipline;
- Have a majority of their tier publications classified under Engineering and Technology;
- Demonstrate recognized awards and achievements within the field.
The D-index threshold is dynamically set in increments of 10 based on the estimated total number of scholars in each discipline, thereby ensuring that the top 1% of leading researchers are incorporated into the ranking. Additionally, candidates were vetted to maintain a proximity of 30% or less between their general H-index and their D-index, validating a strong disciplinary focus in their scholarly output.
Verification and Validation Procedures
Understanding the limitations of raw bibliometric data as an absolute evaluative tool, the Research.com team undertook an extensive manual verification process. All scientist profiles were carefully cross-correlated against publications retrieved from a broad spectrum of authoritative and trustworthy sources to validate their authenticity and accuracy.
While the number of papers published in high-impact journals and reputable conference proceedings does not directly factor into the rank position, it serves as an important secondary indicator of a researcher’s contribution to Engineering and Technology. The ranking’s primary criterion—the D-index—is established using citation data gathered from OpenAlex and CrossRef, recognized as the most comprehensive and widely utilized bibliometric databases in the research community.
