Ph.D student at SEFCOM


2015: EXTREME SDN Innovation challenge (ASU Full Circle, Extreme Blog)

About me

I'm Ph.D student under the supervisory of Dr.Ahn at ASU. I joined SEFCOM lab at 2012 Fall and this is my 4th year of my program. My research interest focuses on the security and policy management in SDN environment.
