Research Interests

  • I am interested in bridging the gap between pure-research and application. My research interests cover memory systems, virtualization, and system security. I have studied solving TLB reach problem in future memory systems. Currently, I am focusing on lowering the cost on memory in collaboration with Microsoft Research Asia.
