A scientist’s position in this ranking is determined by their D-index (Discipline H-index), which is a refined metric focusing exclusively on papers and citations within the examined discipline, effectively isolating their research influence in Mechanical and Aerospace Engineering from their broader scholarly output.
Scope and Eligibility Criteria
The ranking's scope is built upon an extensive evaluation of 279,971 scientist profiles, identified from diverse bibliometric data sources encompassing all research disciplines. Specifically, 2,000+ profiles related to Mechanical and Aerospace Engineering were meticulously examined to devise this list.
- To qualify for inclusion, a scientist’s D-index must be at least 30.
- The majority of their tier publications must be within the Mechanical and Aerospace Engineering domain.
- Awards and recognized achievements specifically in Mechanical and Aerospace Engineering were also considered as important qualitative factors in final assessments.
The threshold D-index value for consideration is adjusted in increments of 10 based on the estimated total number of scholars within each discipline, ensuring that approximately the top 1% of leading experts nationally are incorporated. Additionally, to reflect a researcher's focused impact, there is a guided constraint where the proximity between a scientist’s general H-index and their D-index remains within 30%.
Additional Verification Practices
Recognizing that raw bibliometric data alone is insufficient to fully capture the complexity of scholarly impact, the ranking team conducted rigorous manual verification of all profiles. This process involved cross-correlation against publications from a broad array of trustworthy academic and professional sources to maintain accuracy and authenticity.
While the number of published papers in prominent journals and conference proceedings is not a direct factor influencing the position in the Research.com ranking, it serves as a valuable secondary signal evaluating the researcher’s contribution to the field.
Ultimately, the ranking position is established using each researcher's D-index, based on data sourced from OpenAlex and CrossRef — two of the most authoritative and widely used bibliometric databases available to the global research community.
