A scientist's position in the ranking is determined by their D-index (Discipline H-index), a refined metric that only includes papers and citation counts relevant to the specific discipline under review — in this case, Mechanical and Aerospace Engineering. This targeted approach ensures that the ranking reflects disciplinary excellence rather than general scholarly impact across unrelated fields.
Scope of Research and Qualification Criteria
The ranking assesses a broad scope of scientific profiles, beginning with an initial examination of 279,971 scientist profiles identified from diverse bibliometric data sources across all disciplines. Specifically for Mechanical and Aerospace Engineering, 2,000 scientists were extracted for detailed evaluation.
To qualify for inclusion in the ranking, each scientist must have a D-index of at least 30 in Mechanical and Aerospace Engineering, with a majority of their tier publications concentrated within this discipline. Additionally, awards and other notable achievements in Mechanical and Aerospace Engineering serve as evaluative factors in the selection process.
The threshold for D-index consideration is adjusted in increments of 10, based on the estimated total number of scholars within each discipline, to ensure representation of the top 1% of leading researchers. Furthermore, in order to confirm focused disciplinary expertise, a closeness threshold is applied whereby the difference between a scientist’s general H-index and their D-index does not exceed 30%.
Verification Practices and Ranking Methodology
The Research.com team recognizes the inherent limitations of raw bibliometric data as absolute measures of scholarly output. Therefore, all scientist profiles included in the ranking have undergone manual verification. Each profile was cross-referenced against publications in a wide range of trustworthy and authoritative sources to validate accuracy.
While the number of papers published in prominent journals and conference proceedings does not directly affect a scientist’s ranking position, this metric is considered a valuable secondary indicator of research contribution within the specific field.
The ranking itself is firmly grounded in each researcher's D-index, derived from comprehensive data gathered via OpenAlex and CrossRef — two of the most extensive, well-established, and publicly accessible bibliometric databases utilized by the global research community.
