Research Interests

Make system secure and reliable: Resource contention is awkward. Some abnormal workloads leading the system to severe contention depresses the reliability. Other malicious users making use of the contention to launch DoS attack harms the security. I work toward analyzing and mitigating the contention with some novel mechanisms.

Make secure and reliable system faster: Security is expensive. The software solution costs efficiency. The hardware solution costs money. I seek a co-design approach to accelerate current solutions while making minimal changes to existing hardware.

AI 4 SYS: I have experience in AI research and am eager to combine this expertise with system research.
