Hanju Yoo

I am a Ph.D. candidate at Yonsei University in the Intelligence Networking Lab. My research focuses on AI-native wireless systems, including semantic communications, wireless digital twins, learning-based physical layer design, and real-world wireless prototyping. I have demonstrated real-time wireless prototypes at venues including IEEE GLOBECOM, IEEE ICC, and CES. I earned a B.S. from the School of Integrated Technology at Yonsei University, graduating with the highest honors.
