A central metric to this ranking is the D-index (Discipline H-index), which reflects a researcher's scholarly impact strictly within the examined discipline of Engineering and Technology. The D-index selectively includes only the papers and citation metrics relevant to this specific discipline, thereby providing a focused and accurate reflection of each scientist’s contributions to the field.
Scope of Research and Eligibility Criteria
In total, 279,971 scientist profiles were examined across all scientific disciplines using a range of bibliometric sources. Within this extensive dataset, 18 scientists were specifically identified under the Engineering and Technology category in Pakistan.
To qualify for inclusion in the ranking, a researcher’s D-index had to meet a minimum threshold of 30. Additionally, the majority of their tier publications—those deemed most impactful and visible—were required to fall within the domain of Engineering and Technology. Consideration was also given to scientists’ notable awards and achievements directly associated with this field.
The threshold for the D-index is designed as incremental steps of 10, calibrated proportionally to the estimated number of scholars within each discipline. This approach ensures that the ranking consistently incorporates the top 1% of leading researchers within the respective field. Moreover, a proximity constraint mandates that the difference between a scientist’s overall H-index and their discipline-specific D-index does not exceed 30%, thereby maintaining disciplinary relevance and precision in evaluation.
Verification and Validation Practices
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or impact. To this end, all scientist profiles included in the ranking were manually verified and rigorously cross-correlated against publications indexed in a variety of trustworthy academic sources. This detailed verification process is aimed at eliminating inaccuracies and reinforcing the validity of the ranking.
While the number of papers published in prominent journals and conference proceedings does not directly influence a researcher’s position in the ranking, it is treated as a valuable secondary indicator of their contribution to the scientific community within the specific domain of Engineering and Technology.
Ultimately, the ranking positions are determined by each researcher’s D-index derived from data gathered through OpenAlex and CrossRef, the most prominent and widely respected bibliometric databases available today.
