Taiyo Ushiyama, a first-year doctoral student in the Department of Computer and Network Engineering at UEC, received the Electronics Society Student Award for his research presentation at the plenary session of the IEICE (Institute of Electronics, Information and Communication Engineers) Society Conference, held at Okayama University’s Tsushima Campus in September 2025.
The conference, jointly organized by four IEICE Societies (specialized divisions within the association), provides a forum for discussions on a wide range of technologies in electronics, communications, and information. The award is conferred by the IEICE’s research committee to outstanding presentations in three research fields. Ushiyama was selected from more than 110 presentations in the field of 1. Electromagnetic Theory and Microwaves, and received a certificate of commendation.
