Productivity Rankings is an exclusive service provided by AD Scientific Index. This ranking system, derived from the i10 index, highlights the productivity of scientists in publishing impactful scientific articles. Productivity Rankings serves as a tool to identify highly productive scientists across specific areas, disciplines, universities, and countries, and supports the creation of effective incentives and academic policies. The global, regional, and institutional rankings of scientists in this table are calculated based on their total i10 index. Moreover, you can explore special rankings derived from Productivity Rankings, such as Scientists Last 6 Years' i10 Index, Universities Total i10 Index Rankings 2025, Universities Last 6 Years' i10 Index Rankings 2025, Art and Humanities i10 Productivity Rankings, and Social Sciences and Humanities i10 Productivity Rankings.
