Ph.D. Student @Duke

Biography

I am a third-year Ph.D. student in the Department of Computer Science at Duke University, advised by Prof. Danyang Zhuo. Before Duke, I received my bachelor’s degree from Peking University.

Research

As a member of Duke Systems Group, my research interests include cloud computing and datacenter networks, with a focus on kernel bypass networking and hardware acceleration. Specifically, I lead the project of HostBench, a test framework for RDMA software/hardware stack. The ambition of this project is to assist cloud providers and hardware vendors in building more reliable, efficient, and secure next generations of kernel bypass networks. Our current publications/projects, Husky (NSDI '23) and Collie (NSDI '22), are part of this initiative. We have already seen real-world impact from our work, as vendors have released new CVEs and firmware upgrades in response to the issues we identified. We are now working on generalizing this framework to other kernel bypass network solutions and diverse types of heterogeneous hardware.
