Differential Privacy

Ninghui Li is a professor of computer science at Purdue University. His research interests are in security and privacy. He received a Bachelor's degree from the University of Science and Technology of China in 1993 and a Ph.D. in computer science from New York University in 2000. Before joining the faculty of Purdue in 2003, he was a research associate at Stanford University's Computer Science Department for three years. Prof. Li is Vice Chair of ACM Special Interest Group on Security, Audit and Control (SIGSAC). He is serving, or has served, on the editorial boards of ACM Transactions on Privacy and Security (TOPS), Journal of Computer Security (JCS), IEEE Transactions on Dependable and Secure Computing, VLDB Journal, and ACM Transactions on Internet Technology. He has served on the Program Committees of many international conferences and workshops in computer security, databases, and data mining, including serving as Program Chair for 2014 and 2015 ACM Conference on Computer and Communications Security (CCS), ACM's flagship conference in the field of security and privacy.Min Lyu has been a lecturer in the School of Computer Science and Technology at the University of Science and Technology of China since 2007. She received a Bachelor's degree and a Master's degree in applied mathematics from Anhui University in 1999 and 2002, respectively, and a Ph.D. in applied mathematics from the University of Science and Technology of China in 2005. Before joining the faculty of the University of Science and Technology of China in 2007, she was a post-doctor in School of Computer Science and Technology at the University of Science and Technology of China for two years. She was a visiting scholar at Purdue University in 2015, hosted by Professor Ninghui Li on the topic of differential privacy. Her research interests are in security and privacy, social networks, and combinatorial mathematics.Dong Su is a Ph.D. student in the Computer Science Department at PurdueUniversity.
