Professor Shoryu Katsura received his training in Sanskrit and Buddhist Studies at Kyoto University and the University of Toronto. From 1974 to 2004 he taught in the Department of Indian Philosophy at Hiroshima University; from 2004 he was Professor of Buddhist Philosophy at Ryukoku University, Kyoto, until his retirement in 2012. He remains active at Ryukoku University, where he is Director of their Research Center for Buddhist Cultures in Asia. He is the author or editor of seven books, and has published over sixty articles on various facets of classical Indian Buddhist thought. He is perhaps best known for his work on Buddhist epistemology-the thought of Dignaga, Dharmakirti, and their commentators-but has also made important contributions to the study of Madhyamaka, Abhidharma, and later Mahayana thought. In addition he serves as chief priest of Kodaiji, a small Jodo-shinshu temple in Shiga Prefecture.
