During my research career, I have ever focused on the following areas in computer networking: network security, connectivity of P2P networks, MAC protocols for wireless networks, position-based routing and node deployment algorithms for wireless networks, privacy and trust in online social networks, and energy efficiency in data centre networks. In terms of theories and skills, I have some expertise in graph theory, computational geometry, algorithm complexity, ns-2 simulations, C++ programming, and open source software development . My current research interests lie in:

  • Routing and topology control algorithms for wireless networks
  • Data centre networks
  • Security and trust issues in online social networks
  • Software Defined Networking
  • Energy efficiency in different types of networks.

Very welcome to discuss with me if you share similar research interests. More info about my research can be found at
