Rankings

California Institute of Technology Caltech/ 1,285 Scientists i10 Productivity Rankings - 2025

Total 2,393,018 scientists, country 221, and institutions 24,455 are evaluated in the Productivity Rankings, an exclusive service provided by AD Scientific Index. This ranking measures and highlights the scientific productivity of researchers based on the i10 index (number of publications with at least 10 citations). This system identifies highly productive scientists across disciplines, institutions, and regions, contributing to the development of evidence-based academic policies and effective incentive mechanisms. The rankings include global, regional, and institutional analyses, along with specialized rankings such as Scientists' Last 6 Years' i10 Index and Universities' i10 Index Rankings 2025. With Premium Membership, you can:

  • Gain full access to detailed comparisons and advanced analytics,
  • Objectively evaluate your academic productivity,
  • Make strategic, data-driven decisions to enhance performance.
