Advanced Networking and System Research Laboratory


The Advanced Networking and System Research Laboratory (ANSRLab) is a research group affiliated with Department of Computer Science and Engineering at the Chinese University of Hong Kong. It is led by Professor John C.S. Lui, and comprises a group of energetic PhD students and post-docs. Our research emphasis spans a wide range of theoretical and applied topics in applied machine learning, data analytics, network science, network economics, Internet architecture as well as system/network security. We address the challenging and interesting research problems using both (i) rigorous mathematical and analytical approaches and (ii) extensive system implementation and experiments. Through dedicated research efforts, we seek to make a fundamental impact in the area of computer networking, large scale distributed systems and the Internet.

Unlike other research groups that emphasize on publication, we believe this should not be the ultimate goal. Instead, we believe a good intellectual atmosphere is very crucial. As long as our group members are excited about learning, and actively exploring creative solutions to important problems, then good research work, publication and reputation will follow.

Recruitment: We are recruiting motivated graduate students and post-docs. Please contact Prof. John C.S. Lui via email.

Overview of Research

Our research spans a wide range of interesting theoretical and applied topics, Our current research areas include (but are not limited to):

  • Theoretical/analytical issues:
    • Network science (e.g., information maximization and random walk sampling algorithms for large scale networks, …etc)
    • Network economics problems (e.g., pricing, incentive mechanism designs, ..etc.)
    • Data mining and information extraction on WWW or large scale network economics problems.
    • Online learning algorithms for designing large scale networks and network measurement problems
    • Reinforcement learning and importance sampling theory, and their application to large scale networks and distributed systems.
  • Applied/systems issues:
    • Android system security
    • Network management, measurement, monitoring
    • Internet-of-Things (IoTs)
    • Mobile computing and communications.

Students' Careers

We are dedicated to provide the best educational training for students and make them well-prepared in their careers, either in industry and academia. We are proud to say that students in our group have accomplished significant achievements. Not only their work appear in prestigious international conferences/journals, some of them even won best paper award. Many of them eventually go to prestigious places in academia or industry, including:

  • Academia: Stanford, Columbia, UCLA, USC, UIUC, Princeton, Purdue, CMU, Caltech, Toronto, etc. Including professorial positions at Fudan University, USTC, Tsinghua University,..etc.
  • Industry: IBM, Microsoft, Tencent, Alibaba, EMC, INRIA Research Lab, Outblaze, Barclays Bank, Morgan Stanley, Harmonic Inc, Deutsche Bank, CitiGroup, HSBC, etc.

Please refer to the People page for their careers after graduation.
