A researcher’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that considers only the papers and citation counts specifically within the examined discipline, thereby providing a more precise assessment of individual contributions in Engineering and Technology.
Scope of Research and Eligibility Criteria
The ranking methodology began with an examination of 279,971 scientist profiles identified from a diverse array of bibliometric sources, analyzing research contributions across all disciplines. Within this dataset, 39 scientists specializing in Engineering and Technology were specifically evaluated.
To qualify for inclusion in the ranking, a scientist was required to have a minimum D-index of 30, with the majority of their Tier publications firmly rooted in the Engineering and Technology field. In addition to bibliometric indicators, individual awards and notable achievements within the discipline were also considered to capture the broader impact of a researcher’s work.
The D-index threshold for top researcher consideration is adaptively set in increments of 10 based on the estimated size of the scholarly community within each discipline, guaranteeing representation of the top 1% of leading experts. Furthermore, to ensure disciplinary focus and consistency, a scientist’s general H-index must be within approximately 30% of their D-index.
Verification and Validation Procedures
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the Research.com team subjected all scientist profiles to meticulous manual verification. This process included cross-correlating publication records against a broad spectrum of trustworthy sources to authenticate the accuracy and discipline specificity of each profile.
While the quantity of papers published in prominent journals and conference proceedings does not directly influence a researcher’s rank, it serves as a valuable secondary indicator of their contributions to the Engineering and Technology landscape.
The final ranking positions are established based on the D-index calculated using data from OpenAlex and CrossRef, the foremost bibliometric databases accessible to the global research community.
