Data Sources and Citation Metrics
The 5th edition of the Research.com Best Engineering and Technology Scientists in Malaysia Ranking is built upon comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, along with multiple other reputable data repositories. These databases represent some of the most prominent and well-established bibliometric resources available to the global research community, ensuring a robust foundation for the ranking. The citation-based metrics that underpin the evaluation were meticulously collected on January 12, 2026. Each scientist’s ranking position is determined based on their D-index (Discipline H-index), a specialized metric that exclusively considers publications and citation metrics within the examined discipline, thereby ensuring that assessment is highly relevant and focused on Engineering and Technology.
Scope of Research and Eligibility Criteria
This ranking assesses a total of 279,971 scientist profiles identified across a broad spectrum of bibliometric data sources and disciplines. Specifically, within the field of Engineering and Technology, 112 scientists were evaluated. To qualify for inclusion in this ranking, a scientist’s D-index must be at least 30. Additionally, the majority of their tier publications must fall within the Engineering and Technology discipline. Recognition of awards and significant achievements within this field also played an integral role as supplemental criteria. The threshold for the D-index is dynamically calibrated — set in increments of 10 based on the estimated total number of scholars within each discipline — to ensure that the top 1% of leading researchers in Engineering and Technology are represented. Moreover, to maintain disciplinary relevance, a scientist’s general H-index and their D-index must be in close proximity, with a difference of no more than 30%.
Verification and Additional Evaluation Practices
At Research.com, we recognize that raw bibliometric data should never serve as the sole instrument for evaluating the scholarly output of researchers. Accordingly, all scientist profiles were subject to manual verification and cross-correlation against publications in a diverse array of trustworthy, high-quality sources. While not directly influencing the positioning in the ranking, we consider the number of papers published in prestigious journals and leading conference proceedings as valuable secondary indicators of a researcher’s contribution and standing within the Engineering and Technology community. Each researcher’s D-index, as derived from OpenAlex and CrossRef, forms the quantitative backbone for their ranking placement.
