Seong-Joon Park

Hi, I'm  Seong-Joon Park, a Staff Engineer at Samsung Electronics. I was a Postdoctoral Researcher in Institute of Artificial Intelligence at Pohang University of Science and Technology (POSTECH) hosted by Prof. Yongjune Kim. I received Ph.D. and M.S. degrees in Electrical and Computer Engineering at Seoul National University (SNU), where I was advised by Prof. Jong-Seon No.

My research area focuses on information theory, channel coding, machine learning, and quantum error correction & quantum information theory

• AI/ML-based decoder for error correcting codes

• Quantum error correction & Quantum information theory

• Channel coding for wireless communication and memory systems

Selected Publications
