An institution's position in the ranking is determined by the sum of D-indexes (Discipline H-index) of all ranked scholars directly affiliated with the institution whose primary area of publication is Mechanical and Aerospace Engineering. The D-index is designed to exclusively measure publications and citation data related to the examined discipline, offering a highly targeted evaluation of research influence within Mechanical and Aerospace Engineering.
Scope of Research and Ranking Criteria
The ranking comprehensively analyzed 279,971 scientist profiles identified across a range of bibliometric data sources, with a targeted review of 66,807 scientists working specifically in the area of Mechanical and Aerospace Engineering. To ensure the quality and relevance of the ranking:
- The qualifying D-index threshold for inclusion was set at 30.
- A majority of each scientist’s most influential publications had to fall within the field of Mechanical and Aerospace Engineering.
- Each scientist’s awards and notable achievements in Mechanical and Aerospace Engineering were also carefully considered.
- The D-index threshold for inclusion among top researchers increases by increments of ten, depending on the estimated total number of scholars per discipline, while guaranteeing that the top 1% of leading scholars are included in the list.
- There must be a proximity of 30% or less between a researcher’s overall H-index and their discipline-specific D-index, reinforcing that Mechanical and Aerospace Engineering is their primary area of contribution.
Scientist’s awards and achievements in their field of study were also factored into the assessment, recognizing exceptional contributions beyond citation metrics.
Verification and Quality Assurance
The team behind the ranking acknowledges that raw bibliometric data alone cannot wholly capture the multifaceted impact of a scholar’s academic output. To mitigate this, all scientist profiles were manually verified and cross-checked against publication records in a broad selection of trustworthy sources and repositories. While not a direct metric for ranking, the number of papers published in prestigious journals and conference proceedings is recognized as an important supplementary indicator of a scientist’s influence in their discipline.
Final positions in the ranking are established using each researcher's H-index calculated from both OpenAlex and CrossRef — the foremost and most widely adopted bibliometric databases available to the research community. This dual-source approach ensures a high degree of reliability and minimizes potential biases. For further insights into the methodology, please refer to our methodology page.
