All bibliometric data used in crafting this ranking were collected on January 12, 2026, ensuring the most current and robust representation of scholarly output and impact. An institution's position in the ranking is determined by the cumulative sum of D-indexes (Discipline H-index) of all ranking scholars affiliated with the institution whose primary publication domain is Engineering and Technology. The D-index is a discipline-specific H-index variant, incorporating exclusively publications and citation data pertinent to the examined discipline, thus offering a nuanced and focused evaluation of scholarly influence within Engineering and Technology.
Scope of Research and Selection Criteria
A total of 279,971 scientist profiles were initially identified through a variety of bibliometric data sources. From this broad dataset, 53,176 scientists specializing in Engineering and Technology were rigorously analysed for this ranking. To qualify, each scientist was required to have a D-index threshold of at least 30, with a majority of their tier publications firmly rooted in the area of Engineering and Technology.
In addition to bibliometric criteria, researchers’ awards and achievements within the field were important factors in their consideration. The threshold for the D-index was dynamically set, increasing in increments of 10 relative to the total estimated number of scholars in each discipline, ensuring that the top 1% of leading scholars globally are included in the ranking.
Moreover, to maintain alignment with discipline-focused impact, a proximity criterion was applied wherein a scientist’s general H-index and their discipline-specific D-index must not differ by more than 30%. This rigorous approach guarantees the inclusion of genuinely leading experts with demonstrated excellence in Engineering and Technology.
Verification Practices and Data Integrity
Recognizing that raw data alone can never provide an absolute evaluation of scholarly output, meticulous manual verification was conducted for all scientist profiles considered in the ranking. Each profile was cross-correlated against publications recorded in a wide array of trustworthy sources, ensuring accuracy and integrity.
While the number of papers published in prominent journals and conference proceedings is not used directly to determine a researcher’s ranking position, it serves as a valuable secondary signal reflecting a scientist’s contribution to the advancement of research in their specific area.
Positions in the ranking fundamentally rely on each researcher’s H-index, as derived from the comprehensive data provided by OpenAlex and CrossRef — recognized as two of the most prominent and respected bibliometric databases available to the global research community.
