The position of each university in the ranking is determined by the cumulative D-index (Discipline H-index) of all qualifying scholars affiliated with the institution whose principal area of publication is Electronics and Electrical Engineering. Notably, the D-index metric encompasses only publications and citations specific to the examined discipline, thereby providing a precise assessment of field-specific scholarly output and influence.
Scope of Research and Selection Criteria
To ensure comprehensive coverage and accuracy, the 2024 ranking analyzed 279,971 scientist profiles across diverse bibliometric data sources, with 44,264 researchers identified and analyzed specifically in Electronics and Electrical Engineering. To qualify for assessment, each scientist needed a D-index of 30 or above, and the majority of their tier publications had to be in the field of Electronics and Electrical Engineering. Furthermore, prominent scientist awards and field-specific achievements were also considered to refine the selection of top scholars.
The D-index threshold for identifying top researchers was dynamically set in increments of 10, corresponding to the estimated scholar population per discipline, ensuring that the top 1% of leading scientists were incorporated into the ranking. Additional criteria stipulated that the proximity between a scientist’s general H-index and their D-index should be 30% or less, reinforcing discipline-specific excellence. Notably, field-related awards and recognitions were supplementary factors in the ranking methodology.
Verification Practices and Methodological Transparency
Recognizing that raw bibliometric data alone should not serve as the sole means of evaluating scientific contributions, every scientist profile included in the ranking underwent manual verification and was cross-referenced against publications in a broad spectrum of reliable sources. While the quantity of papers published in prominent journals and conference proceedings is not a formal ranking factor, it is acknowledged as a valuable supplementary indicator of a scientist’s contribution to their discipline.
Ranking positions are established based on each researcher’s H-index information aggregated from OpenAlex and CrossRef—the leading and most reputable bibliometric databases within the global research community.
