Professor Xiuzhen "Susan" Cheng's research spans the broad area of wireless networking and mobile computing. She is currently working on a few projects that tackle the challenges of efficient network resource management, role-based access control and secure communications, dynamic spectrum access, and economically-robust/secure auctions. Professor Cheng is also interested in applying wireless networking to public health. She has been working on target vaccination based on social networks, security and privacy concerns in wireless body area networks, and safety enhancement via vehicle networks.
