Data Sources and Metrics Basis
The 5th edition of the Research.com Best Engineering and Technology Scientists in Peru Ranking is founded on comprehensive bibliometric data derived primarily from the OpenAlex and CrossRef databases, complemented by multiple other reputable data sources. The citation-based metrics utilized to establish this ranking were meticulously collected on January 12, 2026. A researcher's position within the ranking is determined exclusively by their D-index (Discipline H-index), which is a refined variant of the traditional H-index that accounts only for publications and citations pertinent to the examined discipline—in this case, Engineering and Technology.
Scope of Research and Qualification Criteria
The scope of the ranking encompasses a broad spectrum of scientific disciplines. A total of 279,971 scientist profiles identified through various bibliometric data sources were reviewed across all fields of study. Specifically, within the domain of Engineering and Technology, 1,007 scientist profiles were identified and analyzed.
To qualify for inclusion in the ranking, candidates were required to meet the following criteria:
- A minimum D-index of 30, thereby ensuring recognition of substantial disciplinary impact.
- A majority of tier publications concentrated in the area of Engineering and Technology.
- Recognition of awards and professional achievements within the Engineering and Technology domain.
The D-index threshold for identifying top researchers is adaptively set in increments of 10, relative to the total estimated number of scholars within each discipline. This approach ensures that the top 1% of leading scholars are consistently integrated into the ranking. Additionally, a qualification stipulation mandates a proximity of 30% or less between a scientist's general H-index and their D-index, ensuring alignment between overall productivity and disciplinary specialization.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the ranking process incorporates rigorous manual verification. Each scientist profile was cross-correlated against an extensive range of trustworthy publication sources to validate accuracy and authenticity. While not directly influencing the ranking position, the number of papers published in prominent journals and conference proceedings is considered a valuable secondary indicator of a scientist’s contribution to their specific field of science.
The ranking positions are established based on each researcher’s D-index, calculated from highly reputable sources—OpenAlex and CrossRef—currently regarded as the most comprehensive and widely acknowledged bibliometric databases available to the scientific community.
