Dr Jie Zhang

Hi there! I am a Lecturer at the Electronics and Computer Science department. Prior to Southampton, I was a research associate at the University of Oxford and was a postdoc at Aarhus University. I received my Ph.D. from the City University of Hong Kong and visited the EconCS group at Harvard University for six months.
