Embedded Files
I am an assistant professor in Computer Science & Engineering at Kangwon National University(KNU) and I'm leading the CASO(Computer Architecture, Security, and Operating system) Lab. Before joining KNU, I worked as a researcher at Cyber Security Research Division, ETRI.
I am interested in various topics in computer systems including security, architecture and software. I earned my Ph.d in Computer Science from KAIST, under the mentorship of Prof. John Kim.
