Cho, Jaeyoon (조재윤)

I am a theoretical physicist and an assistant professor in the Department of Physics at Gyeongsang National University (GNU).

I got my PhD in physics at KAIST and then worked at KRISS, University College London, Queen's Univerisy Belfast, Imperial College London, KIAS, and APCTP.

As of 2020, I am leading “Quantum Information and Many-Body Theory” group at GNU.
