I am currently an associate professor in Computer Science and Engineering at Pohang University of Science and Technology (POSTECH). Before joining POSTECH, I was a CPU/system architect at Sun Microsystems and Oracle Corporation in Silicon Valley, USA. As a CPU architect in Architecture Group, I worked on performance modeling and verification of Sun/Oracle's recently announced multi-core, multi-threaded SPARC T4 CPUs. I also worked on developing highly scalable cloud computing servers that use state-of-the-art virtual machine technologies. Before joining Sun Microsystems, I earned my Ph.D. degree in Computer Engineering from Carnegie Mellon University. My advisor was Prof. Babak Falsafi and I also closely worked with Prof. James C. Hoe, Prof. Ken Mai, and Prof. Anastassia Ailamaki. At CMU, I worked mostly on defect- and fault-tolerant computer system architectures. I earned my B.S. and M.Eng. degrees in Computer Engineering and Computer Science from Cornell University.
