Bibliometric data for generating the citation-based metrics used in this ranking were collected on January 12, 2026. A scientist’s position within the ranking is determined exclusively by their D-index (Discipline H-index), a specialized metric that calculates the H-index based solely on publications and citation counts within the researcher’s examined discipline. This approach ensures that the ranking reflects scholars’ impact specifically within Electronics and Electrical Engineering, rather than their overall research output.
Scope of Research and Qualification Criteria
The ranking process undertook a rigorous examination of a total of 279,971 scientist profiles sourced from varied bibliometric datasets across all scientific disciplines. Within this extensive set, 15 scientists specializing in Electronics and Electrical Engineering were evaluated in detail. To qualify for inclusion, scientists were required to meet a minimum D-index threshold of 30, with the majority of their tier publications demonstrably focused on Electronics and Electrical Engineering.
In addition to bibliometric indicators, a scientist’s awards and notable achievements within the discipline were also considered to provide a more holistic evaluation of their contributions. The threshold for the D-index is adjusted in increments of 10, calibrated according to the estimated total population of scholars within each discipline, with the overarching goal of incorporating at least the top 1% of leading researchers.
Furthermore, a proximity criterion was applied whereby the difference between a scientist’s general H-index and their discipline-specific D-index must be 30% or less, ensuring the ranking accurately reflects domain-focused research impact.
Verification Practices
The researchers responsible for producing this ranking recognize that raw bibliometric data alone cannot serve as an absolute or definitive measure of scholarly output or quality. Consequently, each scientist profile underwent a manual verification process and was cross-correlated against publications listed in a diverse array of trustworthy sources to confirm validity and relevance.
While the number of papers published in prestigious journals and renowned conference proceedings does not directly influence a researcher’s position in the Research.com ranking, it remains a valuable secondary indicator of a scientist’s contribution to their specific field of study.
The ranking position itself is ultimately determined using each researcher’s D-index derived from authoritative databases including OpenAlex and CrossRef. These sources represent the most reliable and widely accepted bibliometric platforms for scientific evaluation currently available.
