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, 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

Recent Publications (full list)

Prospective Students

I am always looking for bright PhD students to work with me. See here for more information.

Top venues for networked systems

I maintain a list of top conferences/workshops for networked systems sorted by their usual deadlines.
