In a groundbreaking study published in 2019 by Ioannidis et al. in PLoS Biology, the authors conducted a meta-analysis that evaluated nearly 7 million working researchers across 22 scientific fields and 176 subfields, including chemistry, physics, engineering, economics, and business. This analysis laid the foundation for the ongoing recognition of outstanding contributions to science.
As part of this tradition, the 2024 edition of Stanford University’s World’s Top 2% Scientists List features approximately 220,000 leading researchers worldwide. The full list is accessible through the digital commons of Elsevier (DOI: 10.17632/btchxktzyw.7), underscoring the diversity and breadth of scientific expertise represented.
Compiled in collaboration with Elsevier and based on comprehensive data from Scopus, the Top 2% Scientists List employs a range of citation metrics, including the h-index and C-score. This rigorous methodology ensures that those included are recognized for their significant impact within their respective fields. The list is updated annually, providing insights into both career-long achievements and recent contributions, thereby fostering a culture of high-quality research.
Being included in this esteemed ranking enhances a scientist’s reputation and can lead to increased funding opportunities and greater visibility in their field. However, the list is not without its controversies; critics argue that its heavy reliance on citation metrics may overlook the true quality and societal impact of some research. Nonetheless, it remains a vital tool for recognizing scientific excellence and promoting impactful research within a rapidly evolving academic landscape.
Among the distinguished scientists recognized in the latest iteration is Professor Muhammad J. A. Shiddiky, who has been ranked in this prestigious list since 2020. Notably, in 2022 he achieved a remarkable position of 478th worldwide in the subfield of Analytical Chemistry, out of 101,089 scientists. This ranking marks a significant improvement from his previous positions of 652nd (out of 102,767) in 2021 and 777th (out of 87,137) in 2020, reflecting his continued contributions to the field and highlighting the evolving landscape of scientific achievement.
