Yoshiteru Nakamori earned his Ph.D. in applied mathematics and physics from Kyoto University in January 1980. Following a period at Konan University in Kobe, he joined the Japan Advanced Institute of Science and Technology in April 1998 as a professor in the School of Knowledge Science. Since then, he has dedicated himself to advancing knowledge science by integrating principles from systems science. He served as Dean of the School of Knowledge Science at the Japan Advanced Institute of Science and Technology from April 2002 to March 2008. From November 2003 to December 2008, he served as president of the International Society for Knowledge and Systems Sciences. Subsequently, he served as Vice-President of the International Federation of Systems Research from April 2008 to March 2010.

Since April 2010, he has been an academician of the International Academy for Systems and Cybernetic Sciences. His research journey began in systems science, focusing on optimizing measurement techniques, constructing system models, and developing decision-support tools for environmental issues. He then transitioned to knowledge science, applying systems methodology to knowledge management practices and concurrently delving into decision analysis under conditions of uncertainty or ambiguity. Subsequently, he pioneered knowledge synthesis decision-making, crafting a framework that integrates systems thinking and knowledge management principles. Drawing on his original research in knowledge construction methodology, he has lectured on systems thinking and knowledge management at several prestigious universities, including the University of Chinese Academy of Sciences in China, Thammasat University in Thailand, and the Japan Advanced Institute of Science and Technology. He published 23 books, 58 book chapters, 184 peer-reviewed journal papers, and 289 international conference papers.
