Changjae Oh (오창재)

I am a Lecturer (Assistant Professor) at the School of Electrical Engineering and Computer Science (EECS), Queen Mary University of London (QMUL) . I was a postdoctoral researcher at QMUL (May 2018-Aug 2019). I received the PhD degree in Electrical and Electronic Engineering from Yonsei University, South Korea.
