The bibliometric data, which underpins the citation-based metrics used throughout the ranking, was collected as of 2024-11-27. Ranking positions are determined by aggregating the D-indexes (Discipline H-index) of all qualifying scholars affiliated with a given institution whose principal area of publication is Engineering and Technology. It is crucial to note that each scholar’s D-index is calculated solely from publications and citations within the examined discipline, ensuring discipline-specific accuracy and relevance.
Scope of Research and Inclusion Criteria
The scope of the ranking is grounded in the analysis of a broad, representative body of researchers: a total of 279,971 scientist profiles have been identified and examined from a variety of bibliometric data sources, with 50,429 scholars specifically analyzed in the discipline of Engineering and Technology.
Criteria for inclusion stipulate that each scientist must surpass a D-index threshold of 30 and must have the majority of their top-tier publications in the area of Engineering and Technology. Additionally, a scientist's awards and achievements in the field are taken into account. For identification of top researchers, a dynamic D-index threshold is implemented—incremented by 10 according to the scholar population per discipline—ensuring that the top 1% of leading scholars are appropriately recognized. Furthermore, the proximity between a scholar’s general H-index and D-index should remain within 30%, a measure designed to guarantee discipline-specific influence. Awards and distinctions in the field play an ancillary evaluative role in the ranking process.
Verification Practices and Ranking Integrity
The Research.com team recognizes that bibliometric data in its raw form cannot solely define the output or impact of a scholar. Consequently, the data collection process is supplemented by manual verification of all scientist profiles and cross-referencing with an array of reliable publication sources. While the number of papers published in leading journals and conference proceedings does not directly influence a researcher’s ranking position, it is acknowledged as a valuable secondary indicator of a scientist’s contributions to their field.
The final positions in the ranking are established using each researcher's H-index, as derived from data in OpenAlex and CrossRef—two of the most authoritative and widely recognized bibliometric databases available to the research community.
