Data Sources for the Ranking
The 5th edition of the Research.com Best Engineering and Technology Scientists in Switzerland Ranking is primarily derived from comprehensive bibliometric data aggregated from several authoritative sources. The core datasets originate from OpenAlex and CrossRef, two of the most prominent and widely recognized bibliometric databases accessible to the research community. In addition, multiple other data sources have been integrated to ensure robustness and coverage. The bibliometric data used to compute the citation-based metrics were collected on January 12, 2026. A scientist’s position in the ranking is determined by their Discipline H-index (D-index), a refined metric that includes only papers and citation data relevant to the examined academic discipline, providing a more precise reflection of impact within a specialized field.
Scope of Research and Ranking Criteria
The ranking comprehensively examined 279,971 scientist profiles drawn from a broad spectrum of bibliometric data sources across all disciplines. Focusing specifically on Engineering and Technology, 136 scientists were rigorously evaluated. To qualify for inclusion in the ranking, a scientist must possess a D-index of at least 30, with the majority of their tier publications firmly anchored in the field of Engineering and Technology. Additionally, distinctions such as awards and notable achievements within the discipline were factored into the assessment.
The threshold for the D-index employed to identify top researchers is set in increments of 10 relative to the estimated total number of scholars within each discipline, ensuring inclusion of the top 1% of leading experts. Furthermore, to maintain the relevance and accuracy of the specialization metric, a scientist’s general H-index and their D-index are required to be within approximately 30% of each other—thus confirming a close alignment between overall and discipline-specific research impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot capture the entirety of a researcher’s scholarly contributions, the Research.com team has instituted a thorough manual verification process for all scientist profiles featured in the ranking. This process involves cross-checking publication records against a wide array of credible and trustworthy sources to safeguard accuracy and authenticity.
While metrics such as the number of papers published in prominent journals and conference proceedings do not directly influence the researcher’s ranking position, they serve as valuable secondary indicators of scientific contribution within the discipline. Ultimately, the rank ordering is based on each researcher’s D-index, exclusively informed by data harvested from OpenAlex and CrossRef.
