Gwangsun Kim

Assistant Professor @ POSTECH

About

I am an assistant professor at the Department of Computer Science and Engineering, POSTECH. Before joining POSTECH, I worked at Arm on improving Arm processor IPs for server systems.

I earned my Ph.D. (2016) and M.S. (2012) degrees from KAIST in Computer Science under Prof. John Kim, and B.S. degree (2010) from POSTECH in Computer Science and Engineering and Electronic and Electrical Engineering (double major).
