Hi, I'm a Ph.D. student in Computer Science at Georgia Institute of Technology. My research interests include compilers and computer architecture for high-performance and embedded systems. Before joining Tech, I was a member of the research staff at the Electronics and Telecommunications Research Institute (ETRI) from 2005 to 2008, and worked as an intern at the Google compiler team in 2010 and 2011.
