To ensure accuracy and relevance, the bibliometric data used in the construction of citation-based metrics for this edition were collected on 2024-11-27. The methodology underpinning the ranking leverages the cumulative D-indexes (Discipline H-index) of all affiliated scholars whose main publication area is Engineering and Technology at a given institution. The D-index calculation strictly considers publications and citation data specific to the relevant discipline, ensuring a precise evaluation of scholarly impact within Engineering and Technology.
Scope of Research and Inclusion Criteria
The breadth of this ranking is grounded in the analysis of an extensive dataset comprising 279,971 scientist profiles, collated from a broad array of bibliometric data sources. Specifically focusing on Engineering and Technology, a cohort of 50,429 scientists was identified and closely evaluated.
Eligibility for inclusion was governed by a minimum D-index threshold of 30, with the additional requirement that the majority of each scholar’s high-tier publications be within the core discipline of Engineering and Technology. Prominent consideration was also given to scientists' awards and notable field achievements.
The D-index threshold for top researcher consideration increments by 10 based on the estimated population of scholars in each discipline, ensuring that the most elite 1% of contributors are represented. To maintain discipline relevance, a scientist’s general H-index and D-index must fall within 30% proximity. Awards and distinguished professional accomplishments further influenced placement, reinforcing a holistic approach in recognizing scholarly excellence.
Verification and Validation Practices
Recognizing the limitations inherent to raw bibliometric data, the ranking’s architects exercised rigorous quality assurance protocols. Every scientist profile underwent manual validation and was cross-referenced against peer-reviewed publications drawn from a wide range of highly reputable sources, thereby bolstering the reliability of the dataset.
While the volume of articles published in leading journals and conferences was not a direct factor in determining rank, it is recommended as a valuable secondary indicator of a scholar’s contribution and standing in the discipline. The core ranking mechanism is built upon the H-index calculated from datasets aggregated by OpenAlex and CrossRef, both globally respected bibliometric databases.
