I am an associate professor in the Graduate School of Information Science and Electrical Engineering (ISEE), and an affiliate faculty member of School of Engineering, School of Science, and Joint Graduate School of Mathematics for Innovation at Kyushu University in Japan. In ISEE, I am belonging to the multi-agent laboratory. My major research field is multi-agent systems, a subfield of artificial intelligence. More specifically, my research focuses on algorithmic aspects of mechanism design, including resource allocations and social choice. Further information on my research is found at Kyushu University Research Activities Database, Google Scholar, DBLP, and researchmap.
