Though mainly employed in academia, I have actively participated in industrial R&D in recent years. With n-hop technologies, I am developing coding-based network communication technologies.

Network coding introduces a new paradigm for network communication, allowing new packets to be generated in addition to store-and-forward at the intermediate networking devices. Network coding provides a practical and information-theoretic framework for enhancing network communication efficiency. My research in network coding includes two primary aspects:

• Designing low-complexity network coding schemes, such as the BATS code.
• Developing physical layer coding, media access control, transport protocol, congestion control, and other relevant components within the network coding framework.

Finite fields are the major algebraic tool for coding design, but they often result in high computation costs during implementation. Shift-XOR codes can be encoded using (non-cyclic) shift and XOR operations, and decoded using a successive cancellation algorithm that incurs almost the same computation cost as encoding. This approach demonstrates potential for reducing computation costs compared to finite-field operations in diverse coding problems.

• We have shown the shift-XOR design in storage codes, regenerating codes, and network codes, revealing further opportunities for shift-XOR codes.
• We are formulating a theory of utilizing shift and XOR operations for coding design, and are confronting some mathematical challenges.

We are seeking PhD students (with full financial support), who will have the opportunity to work on topics aligned with their own interests. For theoretical research, exceptional mathematical skills (not just knowledge) are essential. For system/experimental research, strong programming and hands-on skills are required.

If you are interested in quantum information please reach out to Prof. Masahito Hayashi, with whom I co-supervise PhD students.

No master's degree is required for the PhD program. See the detailed admission requirements on the CUHK(SZ) website.

Undergraduate students from CUHK(SZ) are welcome to participate in our research projects. We also accept visiting students from other universities who are interested in our PhD program.
