About Me
My research focus is on computer architecture, memory system/management, and system reliability and security. Recently, I have been focusing on memory system security, particularly related to the DRAM devices (e.g., read disturbance errors such as rowhammer/rowpress and covert-/side-channels) and reverse-engineering the operations of commercial processors’ memory controllers. Also, I’m interested in enhancing system reliability against silient data corruptions (SDCs).
