Highly Cited Researchers in Japan and US: Focusing on University of Tokyo, Kyoto University and UCSD

Abstract

In this article, focusing on University of Tokyo (UT), Kyoto University (KU) and UC San Diego (UCSD), we extracted and analyzed the data of academic papers published by the Highly Cited Researchers (HCRs) listed by the Clarivate Analytics in 2014, 15, 16 and 17, respectively. We also obtained the data of their Highly Cited Papers (HCPs) that have top 1% citation in a field. We found that UCSD has larger figures than UT or KU in the number of citation per year per researcher and in the number of HCPs per year per researcher. We also collected information on where each HCR got their Ph.D. and found that the percentage of HCRs who are affiliated in the university at which they got their Ph.D. is 63% in UT, 30% in KU and 3% in UCSD. The number of institutions that gave Ph. D. to the 34 HCRs of UCSD extends over 33 universities. Here we can see that there are much difference between Japan and US, concerning variety of where each faculty got Ph.D.
