Summary

      I am a Ph.D. student researching for AI-based communications and information theory for deep learning at the Intelligence Networking Lab., Yonsei University, Korea. Before joining the lab, I earned a B.E. from the School of Integrated Technology at Yonsei University with early graduation. My research interest includes semantic communications, learned image compression, and neural network architectures.

      I have served as a teaching assistant over two years and have three years of student council experience including the president of School of Integrated Technology and the chief executive committee member of College of Engineering. I also love to solve problems from various fields including social issues and medical challenges, via designing technological solutions.
