The bibliometric data used to devise the citation-based metrics were collected on January 12, 2026. This data collection date ensures the ranking reflects the most current and relevant research activities.
A scientist's position in the ranking is determined exclusively by their D-index (Discipline H-index), which is a refined metric that considers only the papers and citation metrics pertinent to the examined discipline, in this case, Electronics and Electrical Engineering. This discipline-focused approach provides a more accurate measure of a researcher’s impact within their specific field.
Scope of Research and Selection Criteria
The ranking process began with an examination of 279,971 scientist profiles identified from a variety of bibliometric sources spanning all research disciplines. Within this broad overview, 2,000 scientists specifically classified under Electronics and Electrical Engineering were analyzed for inclusion.
To qualify for the ranking, researchers were required to have a D-index of at least 30. Additionally, the majority of their tier publications had to be firmly rooted in the Electronics and Electrical Engineering domain. Alongside bibliometric data, scientists’ awards and other notable achievements in the field were carefully considered to enrich the qualification criteria.
The D-index threshold is dynamically set in increments of 10 relative to the estimated total number of scholars per discipline. This adaptive mechanism ensures that the top 1% of leading experts are included in the ranking, effectively reflecting the highest levels of scientific excellence. Furthermore, to maintain consistency in discipline relevance, a researcher’s general H-index was required to be within approximately 30% of their D-index.
Verification Procedures and Ranking Methodology
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of a scholar’s research output, the researchers responsible for the ranking conducted meticulous manual verification of all scientist profiles. Each profile was cross-referenced with publications indexed in a wide array of trusted academic sources to ensure accuracy and reliability.
Although not a direct factor in determining a researcher’s position within the Research.com ranking, the quantity of papers published in prominent journals and prestigious conference proceedings is considered a valuable secondary indicator of a scholar’s contributions to their specialized area of science.
Ultimately, a researcher’s ranking is established exclusively by their D-index as derived from data gathered through OpenAlex and CrossRef, which are among the most prominent and reliable bibliometric databases accessible to the global research community.
