Research Interests

I work on systems and networking. I lead the NetX Lab. Welcome to visit us!

Our research is/was supported by funding from Research Grants Council (RGC) of Hong Kong, The Chinese University of Hong Kong, City University of Hong Kong, Huawei, Microsoft Research Asia, Azure, Amazon Web Services, etc.

Current Projects

  • ML/DA systems: machine learning and data analytics are important, but system and deployment support of ML/DA is often the bottleneck to real-world use

  • Data center networking: what would the future data center network look like?

    • NetKernel, re-architecting network stack as part of the virtualized infrastructure

    • ML-empowered, how can learning help networking?

Prospective Students and Current Openings

I am always looking for bright and self-motivated PhD students. See here for more details.

[5/2021] I am looking for two postdocs or research associates to start as soon as possible. See here for more details.

Top venues for networked systems
