Seong-Joon Park

Hi :)

I am Seong-Joon Park, a Postdoctoral Research Associate 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

• Coding theory, especially channel coding for wireless communication and storage

  • Forward error correction (FEC), error correcting code

• Optimizing AI/ML-based neural decoders for error correcting code

• DNA-based data storage
