The institutional positions in the ranking were determined based on the aggregate D-indexes (Discipline H-index) of affiliated scholars whose main research area is Engineering and Technology. The D-index reflects exclusively the publications and citation data pertinent to the specified discipline, ensuring that the ranking accurately mirrors contributions within Engineering and Technology.
Scope of Research and Scholar Selection Criteria
The scope of the ranking covers a vast dataset, initially examining 279,971 scientist profiles sourced from a spectrum of bibliometric data providers. From this, 50,429 scientists with a clear specialization in Engineering and Technology were thoroughly analyzed.
For inclusion, scientists needed a qualifying D-index of at least 30, and a majority of their most impactful publications had to be in Engineering and Technology. The consideration of scientists’ awards and achievements in their field further enhances the reliability of the ranking. Importantly, the D-index threshold was incremented by steps of 10 according to the estimated total number of scholars within each particular discipline, guaranteeing that the list robustly incorporates the top 1% of leading researchers.
To further ensure domain-specific excellence, a stringent criterion was applied so that there is a proximity of 30% or less between a scientist’s general H-index and their D-index, reinforcing discipline focus. Awards, recognitions, and other distinctive accomplishments within the field also contribute as qualifying factors, solidifying the authority of the ranking.
Verification Practices for Robust Data Integrity
Research.com places the highest importance on data integrity and methodological transparency. The research team acknowledges that raw bibliometric data alone cannot fully encapsulate the value and contributions of scholars. To counteract the limitations inherent in quantitative data, each scientist’s profile was manually verified and cross-referenced with publications from a wide variety of trustworthy sources.
While the number of articles published in high-profile journals and conference proceedings is not a direct factor in the ranking, it is recognized as a valuable secondary measure of a researcher’s scientific impact. The scholar’s position in the ranking was ultimately determined by their H-index, derived from data provided by OpenAlex and CrossRef, two of the most recognized and comprehensive bibliometric sources available.
