AD Scientific Index analyzes academic studies from 150 countries, 4423 universities/institutions, and 37.534 scientists by using numerous criteria to present results to be used for the evaluation of productivity and efficiency by individuals and institutions. In addition to sorting by the “total H-index” you can find here, you can examine several rankings and analyses by the "last 6 years H-index", "total i10 index", "last 6 years' i10 index", "total number of citations", and “last 6 years’ citations”.
