Data Sources and Basis of Ranking
The 5th edition of the Research.com Best Materials Science Scientists in Pakistan Ranking is grounded in comprehensive bibliometric data that were primarily sourced from OpenAlex and CrossRef, supplemented by multiple other authoritative databases. The bibliometric data used to devise the citation-based metrics were collected on January 12, 2026. Each scientist's position within the ranking is determined by their D-index (Discipline H-index), an advanced metric that considers only the papers and citation impact within the specific discipline under examination—in this case, Materials Science—ensuring a focused and relevant assessment of scholarly output.
Scope and Criteria of Research Evaluation
This ranking is the product of a thorough examination of 279,971 scientist profiles collated across various bibliometric data sources covering all disciplines, including 12 scientists specifically identified in the field of Materials Science. To qualify for inclusion, a researcher must have a minimum D-index of 40, with the majority of their tiered publications clearly falling within the Materials Science domain. Additionally, notable awards and achievements related to Materials Science were also considered as part of the evaluation process.
The threshold for D-index inclusion is dynamically set in increments of 10, reflective of the estimated discipline population size, and is calibrated to include at least the top 1% of leading scholars in each field. Furthermore, to ensure disciplinary alignment, the proximity between a scientist’s overall general H-index and their D-index must not exceed 30%, thereby safeguarding the specificity of the ranking to Materials Science research.
Verification and Validation Practices
Recognizing the limitations inherent in raw bibliometric data, the research team behind this ranking undertook meticulous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a wide range of trusted and reputable sources to verify accuracy and authenticity. Although the number of publications in high-impact journals and premier conference proceedings does not directly influence a researcher’s ranking position, it is regarded as a valuable secondary indicator of their contribution to the field.
The final position in the ranking is primarily established using each researcher’s D-index, derived from data gathered from OpenAlex and CrossRef—two of the most prominent and widely utilized bibliometric databases accessible to the global research community.
