A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that exclusively accounts for a researcher’s publications and citations within the examined discipline of Engineering and Technology. This ensures a focused and discipline-specific evaluation of academic impact.
Scope and Selection Criteria
The ranking considered a total of 279,971 scientist profiles aggregated from a broad spectrum of bibliometric data sources across all academic disciplines. Within the specific domain of Engineering and Technology, 109 scientists were examined in detail.
To qualify for inclusion in the ranking, a scientist’s D-index needed to be at least 30, and a majority of their highly ranked publications (tier publications) had to be situated within the Engineering and Technology field. Additionally, an individual’s awards and notable achievements in this specific discipline were factored into the evaluation process.
The threshold for the D-index to identify top researchers was set in increments of 10, calibrated according to the estimated total number of scholars per discipline. This approach guarantees the inclusion of the top 1% of leading scholars, while also ensuring a reasonable proximity—specifically, 30% or less—between a scientist’s general H-index and their D-index. This measure preserves consistency and disciplinary relevance in the ranking results.
Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot provide a definitive evaluation of scholarly output, the ranking process includes rigorous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a wide array of trustworthy and authoritative sources to ensure accuracy and reliability.
While the number of papers published in prominent journals and conference proceedings is not a direct factor influencing the researcher’s position in the Research.com ranking, it serves as a valuable secondary indication of scholarly contribution and engagement within the Engineering and Technology field.
The final ranking is established based on each researcher’s D-index, derived from comprehensive information sourced from OpenAlex and CrossRef—two of the most prominent and respected bibliometric databases accessible to the global research community.
