An institution's position in the ranking is determined by aggregating the D-indexes (Discipline H-index) of all top-ranking scholars affiliated with that institution, whose primary publication area falls under Engineering and Technology. The D-index is formulated using publication and citation data that are specific and exclusive to the discipline being examined, ensuring disciplinary precision in the ranking calculations.
Scope of Research Analyzed
To establish the ranking, a comprehensive analysis of 279,971 scientist profiles sourced from a range of bibliometric data providers was conducted. Out of these, 50,429 scientists were identified as having significant contributions specifically within Engineering and Technology. For each scientist to qualify, a minimum D-index threshold of 30 was required, and the majority of their key publications needed to be in Engineering and Technology.
Alongside bibliometric criteria, scientists' awards and achievements in Engineering and Technology were also carefully considered. The D-index threshold for inclusion among top researchers was set in increments of 10, scaled to the total number of scholars estimated within each discipline. This ensures that the ranking captures at least the top 1% of leading scholars globally. Additionally, only those scientists whose general H-index and D-index were within a proximity margin of 30% or less were considered, further corroborating the relevance and specialization of their contributions. Excellence in professional recognition and field-specific achievements were weighed alongside these quantifiable metrics.
Additional Verification and Validation
Recognizing that quantitative data alone cannot holistically reflect a scholar’s impact, all profiles included in the ranking underwent a rigorous process of manual verification and cross-correlation against multiple trusted sources of scholarly publications. The evaluative process accounted for the publication of articles in prominent journals and conference proceedings, which, while not a direct factor in the Research.com ranking, serve as valuable indicators of a researcher’s impact and productivity within Engineering and Technology.
The ranking's foundation—the H-index and corresponding D-index—was calculated based on data from OpenAlex and CrossRef, two of the most established and credible bibliometric databases available to the academic community. These practices ensure both reliability and transparency in our methodology.
