Rankings for Scientist

More Than a Ranking

NASA Johnson Space Center Scientists Rankings 2024

The international independent ranking organisation AD Scientific Index is more than an ordinary "Ranking". The "AD Scientific Index" analyses the academic work of scientists using the H-index, i10 index and number of citations, and provides results that can be used to evaluate the productivity and efficiency of individuals and institutions. In addition to ranking according to "total H-index" for individuals and institutions, you can also see the ranking and analyses according to "last 6 years H-index", "total i10 Productivity index", "last 6 years i10 Productivity index", "total citations" and "last 6 years citations" only in "AD Scientific Index". See also: Subject Rankings, University Subject Rankings and  Universities Rankings 2024 (Sort by: Last 6 years H Index).   Click here for individual or institutional registration.
