During my research career, I have ever focused on the following areas in computer networking: network security, connectivity of P2P networks, position-based routing and node deployment algorithms for wireless networks, privacy and security in online social networks, and energy efficiency in data centre networks. In terms of theories and skills, I have certain expertise in complex networks, computational geometry, machine learning, blockchain, and open source software development. My current research interests lie in:

  • Cyber Security
  • Data centre networks
  • Internet of Things
  • Software Defined Networking
