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.
