Research

Dr. Chai's research spans across heterogeneous networks, including wired/wireless networks and cyber physical systems.

His current research interests include:

* Information-centric Networking (ICN) - Name-based resolution systems, in-network caching, information resilience.

* Communications in Cyber Physical Systems - Communication infrastructures for smart grid applications.

* Network Science - Complex networks, epidemic theory.

He was previously involved in research on quality of service, resource management (e.g., for satellite networks and wireless mesh networks), cross-layer design (specifically on interaction of protocols at different layers), traffic engineering, and network optimization.

He is always looking for PhD students who have great potential. If you are interested, please contact Dr. Chai with your CV in order to advise you for the possibility of funding.
