According to the 2025 edition of the study coordinated by Professor Ioannidis (Stanford University, USA), 37 researchers from CICECO – Aveiro Institute of Materials are recognized among the world’s leading scientists.

Known as the Stanford World’s Top 2% Scientists, this prestigious study analyses standardized citation indicators, including total citations, h-index, co-authorship-adjusted hm-index, and a composite indicator that accounts for authorship position while minimizing the impact of self-citation. Data are extracted from Elsevier’s Scopus database and updated until the end of 2024.

The study covers 22 scientific areas and 174 disciplines, producing two complementary rankings:

• Single-Year 2024 Performance, focused exclusively on performance during 2024.
• Career-Long Performance, evaluating influence and impact over the entire scientific career.

Single-Year 2024 Performance

In this category, which evaluates researchers based solely on their performance in 2024, 31 CICECO scientists are listed among the world’s top 2%. 

This result represents a 48% growth in the last six years.

This year’s results highlight the strong international visibility of CICECO, with two new names joining the ranking.

Furthermore, 12 CICECO researchers appear in the Top 5 in Portugal within their respective sub-fields, confirming the Institute’s leadership at national level.

Career-Long Performance

In the analysis of scientific impact throughout the career, 27 CICECO researchers are ranked among the 230,333 most influential scientists worldwide.

The 2025 edition introduces two new entries from CICECO compared with 2024. Overall, this represents a 22% growth in the last four years.

Within this career-long assessment, 12 CICECO scientists hold positions in the Top 5 nationally in their sub-fields, reflecting the CICECO’s sustained excellence over time.
