Algorithm design and analysis, Internet of Things, privacy, big data, cognitive radio networks


Dr. Zhipeng Cai received his Ph.D. and M.S. degrees from the Department of Computing Science at the University of Alberta and his B.S. degree from Beijing Institute of Technology. Dr. Cai is currently an assistant professor in the Department of Computer Science at Georgia State University. Prior to joining GSU, Dr. Cai was a research faculty member in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. Dr. Cai is the recipient of an NSF CAREER Award.

Dr. Cai’s research focuses on algorithm design and analysis, the Internet of Things, privacy, big data, and cognitive radio networks. Dr. Cai is particularly interested in developing consumer-aware privacy protection mechanisms for the Internet of Things, designing routing protocols and algorithms for cognitive radio networks considering the social activities of primary users and secondary users, and investigating big data management for wireless sensor networks.
