Tokyo University of Science Scientist Rankings 2023

AD Scientific Index analyzes academic studies from 1 countries, 1 universities/institutions, and 193 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”. Please read the methodology section for “Limitations and Possible Reasons Why a Scientist Is Not on This List”. Click for individual or institutional registration.
