The bibliometric data utilized to compute the citation-based metrics were collected on January 12, 2026, ensuring the most current and relevant information was incorporated into the analysis. A scientist’s position within the ranking is determined by their Discipline H-index (D-index), a refined metric that exclusively reflects papers and citation impact within the examined discipline of Engineering and Technology. This focus ensures the ranking accurately represents contributions specific to the field.
Scope of Research and Selection Criteria
The ranking examines a total of 279,971 scientist profiles identified from diverse bibliometric sources across all academic disciplines. Within this broad dataset, 2,000 scientists specifically recognized in the field of Engineering and Technology were analyzed in detail.
To qualify for inclusion in the ranking, a scientist must meet the following criteria:
- A minimum D-index of 30, reflecting substantial research impact within the discipline.
- A majority of their high-tier publications must be classified within Engineering and Technology.
- Recognition of specialist awards and achievements pertinent to the Engineering and Technology field.
The threshold for the D-index is dynamically set in increments of 10 based on the estimated total number of scholars within each discipline, thereby ensuring that the ranking captures the top 1% of leading researchers. Additionally, to maintain consistency and relevancy, a scientist’s overall H-index and D-index must be in close alignment, with a permissible difference of no more than 30%.
Verification and Validation Procedures
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly achievement, the Research.com team has implemented stringent verification practices. Each scientist’s profile was manually reviewed and cross-correlated with publications in a wide spectrum of trustworthy academic sources.
While the number of publications in prestigious journals and conference proceedings does not directly influence a researcher’s ranking position, it constitutes a valuable secondary signal of a scientist’s contributions within their specific field. The primary ranking metric remains the D-index as extracted from OpenAlex and CrossRef, reflecting rigorous adherence to objective, data-driven measures.
