Data Sources and Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Georgia Ranking is primarily based on bibliometric data collected from leading academic databases, including OpenAlex and CrossRef, supplemented by multiple other reputable data sources. The bibliometric data utilized for devising citation-based metrics were gathered on January 12, 2026. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citations within the specific examined discipline, ensuring a focused and accurate assessment of disciplinary impact.
Scope of Research and Qualification Criteria
The ranking evaluates a comprehensive set of scientist profiles encompassing all disciplines. Specifically, 279,971 scientist profiles were examined across multiple fields of study, with 1,000 scientists identified within the Engineering and Technology discipline. To qualify for inclusion in this ranking, a researcher must possess a D-index of at least 30. Additionally, a majority of their tier publications must originate from the field of Engineering and Technology. Consideration is also given to scientists’ awards and achievements relevant to the discipline.
The D-index threshold is dynamically set as an increment of 10 based on the estimated total number of scholars within each discipline. This approach guarantees inclusion of the top 1% of leading researchers in the respective field. Furthermore, a proximity criterion is applied to ensure disciplinary focus by requiring the difference between a scientist’s general H-index and their D-index to be no more than 30%.
Additional Verification Practices
The researchers responsible for this ranking recognize that raw bibliometric data alone cannot fully capture the scope and quality of scholarly output. Therefore, all scientist profiles were manually verified and cross-correlated against publications listed in a wide range of trustworthy academic sources. While the primary factor determining ranking positions is the D-index derived from OpenAlex and CrossRef data, the number of papers published in prominent journals and conference proceedings is also considered a valuable secondary indicator of contribution within a particular scientific area.
Positioning in the ranking reflects rigorous analysis using the D-index metric from the most prominent and authoritative bibliometric databases available to the research community. Detailed information on the methodology and data processing can be found on our methodology page.
