Additional bibliometric data sources supplement the core datasets to enhance accuracy and coverage. Bibliometric data were systematically collected on January 12, 2026, ensuring the ranking reflects the most current scientific outputs and impact.
A scientist’s position within this ranking is determined by their D-index (Discipline H-index), an adapted version of the traditional H-index that considers only papers and citation metrics directly relevant to the specific discipline under examination — in this case, Electronics and Electrical Engineering. This discipline-specific focus ensures that the ranking accurately highlights expertise within the targeted research area.
Scope of Research and Qualification Criteria
To develop a robust and representative ranking, a total of 279,971 scientist profiles spanning all academic disciplines were initially examined through extensive bibliometric datasets. From this broad pool, 191 scientists specializing in Electronics and Electrical Engineering were identified for detailed evaluation.
Eligibility for inclusion in the ranking required each candidate to meet a minimum D-index threshold of 30. Furthermore, a majority of each scientist’s tier publications needed to be within the domain of Electronics and Electrical Engineering, ensuring disciplinary relevance. Recognition of awards and notable achievements in the field was also considered as an additional qualitative factor.
The D-index threshold is calibrated in increments of 10 based on the estimated total number of scholars within each discipline, guaranteeing inclusion of the top 1% of leading experts. Additionally, a maximum proximity threshold of 30% was enforced between a scientist’s general H-index and their discipline-specific D-index, reinforcing the alignment between overall scholarly impact and discipline-specific contribution.
Verification and Validation Practices
At Research.com, we recognize that raw bibliometric data alone cannot fully capture the complexity and nuances of individual scientific contributions. Therefore, all scientist profiles incorporated into the ranking underwent rigorous manual verification. This process involved cross-referencing publications and achievements against a wide range of reputable sources, including prominent journals, conference proceedings, and institutional repositories.
While the quantity of papers published in highly regarded venues does not directly influence a researcher’s D-index or ranking position, it serves as an important secondary indicator of a scholar’s research significance within Electronics and Electrical Engineering.
Ultimately, the ranking positions are established based on the D-index calculated from data sourced primarily from OpenAlex and CrossRef. These platforms remain the cornerstone data providers utilized in the methodology, balancing comprehensive coverage with data integrity.
