Kuo-lung Yu holds a Ph.D. in International Politics from Peking University, where he also completed his postdoctoral research in Political Science. He is currently Professor at the School of International Relations and Deputy Director of the Institute of Psychoculturology at Huaqiao University.

Prof. Yu has long been engaged in the development of Psychoculturology, a transdisciplinary paradigm that integrates psychological, cultural, and social-structural dimensions in the comparative analysis of human behavior. Building on the theoretical foundation laid by Francis L. K. Hsu, he has contributed significantly to the systematization of this field. He is the originator of the “Relational Ascription Theory of Ethnic Identity” and the “Social Structure Continuum Theory,” which provide rigorous methodological tools for analyzing the interaction between micro-level ethnic interactions and macro-level social structures. His research spans comparative civilization studies, ethnic relations, identity politics, interpersonal behavior, and international relations, with a particular focus on Chinese, American, Japanese, and Hindu cultural systems.

He is the author of the landmark monograph The Paradigm Revolution of Francis L. K. Hsu: Theories and Methods for the Comparative Study of Literate Civilizations (Springer Nature, 2026). His other major works including Psychoculturology: Studies and Applications of Francis L. K. Hsu’s Theories (2010), A Study on Francis L. K. Hsu’s Comparative Theory of Literate Civilizations (2014), A Survey of the Influence of Chinese Culture in India (2019), and The Japanese and the Japanese State: A Psychoculturological Perspective (2021). In addition, he has published extensively on topics such as soft power, international relations theory, and Japanese studies.
