Institutional positions in this ranking are determined by aggregating the D-indexes (Discipline H-index) of all evaluated scholars who are affiliated with an institution and whose primary publication area is Electronics and Electrical Engineering. The D-index exclusively considers publications and citation data within the specific discipline, ensuring a focused and accurate reflection of subject-matter expertise.
Scope of Research and Selection Criteria
Drawing from a vast pool of bibliometric data, this edition analyzed 279,971 scientist profiles identified across various data sources. Specifically, 44,264 scientists specializing in Electronics and Electrical Engineering were closely examined. To maintain rigor and relevance, the qualifying D-index threshold for each scientist was set at 30, and a majority of their premier publications had to be in Electronics and Electrical Engineering.
Additionally, recognition of scientists through awards and field-specific achievements contributed as qualitative factors. The D-index threshold for consideration of top researchers is adjusted in increments of 10, depending on the total number of scholars within each discipline. This dynamic threshold is designed to guarantee that at least the top 1% of leading scholars are incorporated into the list. Furthermore, to ensure discipline specialism, a proximity of 30% or less between a scientist’s general H-index and their D-index is required.
Awards and distinguished achievements in Electronics and Electrical Engineering also play a valuable role in the evaluation process, adding further credibility and nuance to the ranking.
Verification Practices and Data Validation
Research.com recognizes that quantitative metrics alone are insufficient for assessing scholarly impact in its entirety. To uphold the highest standards, every scientist’s profile was subject to manual verification and cross-checking against an array of reputable publication sources.
While the number of papers published in prestigious journals and conference proceedings does not directly influence a researcher's position in the ranking, it is recognized as an important secondary indicator of a scientist’s contribution to their field. Rankings are ultimately determined based on each researcher's H-index information, rigorously collected from OpenAlex and CrossRef—the two preeminent bibliometric databases leveraged by the global research community.
