Dr. Sungjun Ahn, an alumnus of the Advanced Radio Technology (ART) Lab in the KAIST School of Electrical Engineering (Advisor: Prof. Joonhyuk Kang), has been appointed as a tenure-track faculty member in the Department of Artificial Intelligence and Information Technology at Sejong University, effective September 1, 2026.
Dr. Ahn received his B.S., M.S., and Ph.D. degrees from the School of Electrical Engineering, KAIST. He has been with the Media Research Division, Electronics and Telecommunications Research Institute (ETRI) since 2017, where he has served as a Senior Research Engineer and Research Fellow Board Member. His work has focused on digital terrestrial broadcasting systems, broadcast-broadband convergence, semantic media, and terrestrial time-transfer technologies. His doctoral dissertation, “On the Convergence and Applications of Broadcast and Broadband: System and Network Design Perspectives,” received the Outstanding Ph.D. Dissertation Award from the KAIST College of Engineering.
Dr. Ahn has made substantial contributions to the development and international standardization of ATSC 3.0 physical-layer technologies. In particular, he served as a principal drafter of the ATSC 3.0 MIMO Extension amendment and contributed to the world’s first commercial deployment of terrestrial MIMO broadcasting technology. He also played a leading role in the physical-layer standardization of Brazil’s new terrestrial broadcasting standard, DTV+, resulting in the final adoption of the ATSC 3.0 MIMO Extension as Brazil’s national physical-layer standard.
For his research and international standardization contributions, Dr. Ahn received the ETRI 50th Anniversary Outstanding Researcher Award as its representative recipient, the Grand Prize of the ETRI Foundational Patent Award, the ETRI Young Researcher Award, the High-Impact International Standard Technology Award, and a Commendation from the Minister of Science and ICT. In 2025, he was selected as an ETRI Next-Generation Leading Young Researcher.
Since 2022, Dr. Ahn has also served as an Associate Editor of IEEE Transactions on Broadcasting, a leading international journal in broadcasting and multimedia. He has authored more than 100 technical publications and patents.
Moving forward, Dr. Ahn will pursue research at the intersection of wireless communications, media, artificial intelligence, and information theory, with an emphasis on connecting theories with physical systems, practical applications, and international standards.
