Biography

Assistant Professor of Sejong University since 2026,
Senior Research Engineer of ETRI from 2017 to 2026,
Research Fellow Board Member of ETRI from 2024 to 2025.
Associate Editor of IEEE Transactions on Broadcasting

Has participated in: System design, implementation, field verifications, standardization, and theoretical analyses for media broadcasting and wireless system applications.

Proposed: A series of standard technologies adopted into the ATSC 3.0 Physical Layer standard
(System designs for the extended use of MIMO in ATSC 3.0: Related to NOMA, MIMO, channel bonding, etc.).

Major drafter of ATSC 3.0 MIMO Extension standard specifications

Contributed to: The Brazilian TV 3.0 (DTV+) standardization, where ATSC 3.0 augmented with the proposed designs above was selected as the new Brazilian broadcasting standard.

Proposed: A semantic media protocol architecture for generative AI-powered media systems.

Currently contributing to: ATSC 3.0 standardization projects, research activities on terrestrial time transfer systems (BPS), semantic AI media protocol, and multiplexed coexistence of broadcasting and 5G. 

Interests: Stochastic analysis, signal processing, and optimization for wireless communications and digital broadcasting.
