Data Sources and Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Egypt Ranking is primarily based on bibliometric data sourced from OpenAlex and CrossRef, supplemented by multiple other reputable academic and bibliometric databases. The citation-based metrics used to formulate this ranking were collected on January 12, 2026, ensuring the data reflects the most current scholarly output. The ranking methodology specifically uses a researcher’s D-index (Discipline H-index), which considers only the papers and citation metrics relevant to the examined discipline, providing a focused and discipline-sensitive evaluation of scientific impact.
Scope and Criteria of the Ranking
For this edition, a total of 279,971 scientist profiles identified from diverse bibliometric databases across all disciplines were rigorously analyzed. Within the field of Engineering and Technology specifically, 31 scientists met the criteria and were assessed. To qualify for inclusion in the ranking, a researcher’s D-index needed to be at least 30, and a majority of their key publications had to be centered in Engineering and Technology. Awards and recognized achievements in the field also contributed to the evaluation process.
The D-index threshold for considering top researchers is adjusted in increments of 10 according to the estimated total number of scholars within each discipline, guaranteeing that the top 1% of leading experts are captured in the list. Additionally, there is an expectation that the disparity between a scientist’s general H-index and their D-index does not exceed 30%, ensuring the scientist’s impact within the discipline aligns closely with their overall scholarly influence.
Verification and Validation Practices
The Research.com team acknowledges that raw bibliometric data alone is insufficient to comprehensively evaluate a scholar’s output. Therefore, all scientist profiles included in the ranking were manually verified and cross-referenced against publications from a wide range of trusted academic sources. Although the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s rank, it serves as a valuable secondary signal that reflects the contribution and relevance of a scientist’s research within their specific area of science.
The ranking position is ultimately determined by each researcher’s D-index, utilizing data from OpenAlex and CrossRef — the most authoritative and widely recognized bibliometric databases available to the research community.
