A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively accounts for papers and citation metrics relevant to the specific discipline under examination. This tailored approach ensures that the ranking highlights specialists who have significant scholarly influence specifically within the field of Engineering and Technology.
Scope of Research and Eligibility Criteria
In compiling this ranking, a total of 279,971 scientist profiles from a diverse array of bibliometric databases were analyzed across all scientific disciplines. Within this expansive pool, 1,254 scientists specializing in Engineering and Technology were specifically examined for inclusion in the ranking.
To qualify, scientists must have achieved a D-index of at least 30, reflecting a substantial level of scholarly output and impact within Engineering and Technology. Additionally, a majority of each qualifying scientist’s tier publications were required to be concentrated in this discipline, ensuring their specialization aligns with the field. Consideration was also given to notable awards and achievements relevant to Engineering and Technology.
The D-index threshold for selection is dynamically set in increments of 10 relative to the estimated total number of scholars within each discipline. This approach ensures that the top 1% of leading researchers in each field are effectively incorporated into the ranking. Moreover, the methodology requires that the difference between a scientist’s overall H-index and their Discipline-specific D-index does not exceed 30%, maintaining coherence in their specialized research impact.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture the quality and impact of scholarly contributions, the Research.com team undertook meticulous manual verification of all scientist profiles. Each profile was cross-correlated with publications listed across a broad spectrum of trustworthy sources to confirm accuracy and reduce potential biases or errors.
While the number of publications in prominent journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as an important secondary indicator of their contribution to the field. This layered evaluation ensures comprehensive recognition of scholarly excellence beyond citation counts alone.
Ultimately, the ranking positions are established based on each researcher’s D-index, primarily leveraging data integrated from OpenAlex and CrossRef—two of the most respected and widely used bibliometric databases available to the global research community.
