I am currently a Ph.D. candidate of Computer Science in College of Computing at Georgia Institute of Technology. My supervisor is Professor Karsten Schwan. I am working as a research assistant in Center for Experimental Research in Computer Systems (CERCS). Before that, I was a R&D Engineer in IBM China Research Laboratory(IBMCRL).I graduated with a master degree in Computer Science from Huazhong University of Science and Technology. My supervisor during master study is Professor Hai Jin
My research interests broadly span the areas of distributed systems, data center and virtualization with a current focus on performance troubleshooting for enterprise data center management.
