A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that includes only those publications and citation counts relevant to the specific discipline under examination—in this case, Engineering and Technology. This approach ensures the focus remains on a researcher’s output within their specialized field.
Scope of Research and Eligibility Criteria
The ranking process involved a thorough examination of 279,971 scientist profiles derived from a variety of bibliometric data sources covering all academic disciplines globally. Specifically, within the domain of Engineering and Technology, 2,000 scientists were closely evaluated.
To qualify for inclusion in the ranking, a scientist was required to have a D-index of at least 30, indicating substantial scholarly impact within Engineering and Technology. Additionally, a majority of their tier publications had to be within the scope of this discipline. Consideration was also given to notable awards and achievements related to Engineering and Technology, reinforcing the importance of recognized excellence alongside bibliometric measures.
The threshold for the D-index is calibrated as an increment of 10, based on the estimated total number of active scholars in each discipline, with the objective of consistently including the top 1% of leading researchers. To ensure relevance and discipline-specific excellence, a scientist’s general H-index and their D-index must exhibit a proximity of 30% or less, balancing overall research influence with specialized impact.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully capture the nuanced contributions of scholars, all scientist profiles included in this ranking underwent meticulous manual verification. This process involved cross-correlating individual publication records against a wide range of trustworthy sources to confirm accuracy and authenticity.
While the number of papers published in leading journals and conference proceedings does not directly affect a scientist's ranking position, it remains a valuable secondary signal indicating a researcher’s contribution and standing within a specialized area.
The ranking positions are ultimately established based on each researcher’s D-index derived from the curated information collected predominantly from OpenAlex and CrossRef, two of the most recognized and reliable bibliometric databases available to the scientific community.
