Here is a list of possible PhD projects I am interested in supervising, contact me at if you are interested.

Privacy-Preserving Computing

Study effective methods and techniques for privacy protection for different types of data and for performing computation and data mining tasks on sensitive-information protected data. Recent focuses include privacy protection for location and SMS data in mobile systems and for big data in cloud environment, privacy-preserving classification and clustering.

Network Security

Study effective models, methods and techniques for network intrusion detection, security hole diescuvery, and secure network management. Recent focuses include injecting noise through wavelet transform to protect sensitive information and detecting anomalies through deep learning to discover intrusions and security holes at an early state so that proventive means against attacks may be adopted.

Secure Data Sharing in Social Networks

Study effective methods and techniques for secure data publishing, accessing/searching and propagation in social networks. Recent focuses include social network structural information protection, secure searching, information propagation, and secure recommendation system design.

Survivable Network Design

Study effective methods and techniques for design and analysis of survivable network architectures and communication protocols. Recent focuses include approximation algorithms for computing Steiner networks and for disjoint path routing.

Network Optimization

Study effective methods and techniques for various network optimization problems on allocation and scheduling that are of application importance. Recent focuses are on optimal/approximation schemes for min-movement barrier-coverage under the deployment of mobile sensors and for max-delivery data broadcasting in multi-channel MIMO broadcast network.

Data Center Networks and Cloud Computing

Study effective models and methods for server interconnection and task scheduling in high performance data center networks and for resource allocation in cloud computing environments. Recent foucses include green-energy constrained cost minimisation for multi-source power supply, resource allocation for batch jobs and VM placement in cloud systems.
