A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only those publications and their citation counts within the specific discipline under examination—in this case, Engineering and Technology. This approach enables a focused evaluation that reflects a researcher’s impact within their core area of expertise.
Scope of Research and Qualification Criteria
This ranking encompasses a broad scope of scientific inquiry, beginning with an initial pool of 279,971 scientist profiles identified across all disciplines through various bibliometric sources. Within this extensive dataset, a targeted subset of 85 scientists specializing in Engineering and Technology was rigorously evaluated.
To qualify for inclusion in this ranking, a scientist’s D-index was required to be at least 30, ensuring recognition of only those with a substantial body of highly cited work in the field. Moreover, a majority of a scientist’s top-tier publications had to be demonstrably situated within the Engineering and Technology domain. Beyond bibliometric indicators, scientists’ awards and notable achievements related specifically to Engineering and Technology were considered as supplementary evidence of their contributions.
The D-index threshold for top researchers is dynamically set in increments of 10, calibrated according to the estimated total number of scholars within each discipline. This method guarantees that the top 1% of leading scholars are consistently included. Additionally, care was taken to ensure that each scientist’s general H-index and their discipline-specific D-index exhibited a proximity of 30% or less, thus maintaining alignment between overall scholarly impact and domain-specific influence.
Additional Verification Practices
The team responsible for this ranking acknowledges that raw bibliometric data alone cannot fully encapsulate the quality and impact of a scholar’s research output. Consequently, all scientist profiles underwent meticulous manual verification. This process involved cross-correlating publication records against a wide array of reputable academic sources to validate authorship and relevance.
While not directly influencing the scientist’s position within the Research.com ranking, the presence of publications in prominent journals and key conference proceedings serves as an important secondary signal, reinforcing a researcher’s standing and contribution to the specific scientific field.
The scientific community is encouraged to explore the detailed methodology that underpins this ranking, grounded in the most authoritative bibliometric data from OpenAlex and CrossRef. Further information can be found on our methodology page.
