September 05, 2017

Dr. Xiuzhen (Susan) Cheng is the lead PI and PI, respectively, on two recent National Science Foundation (NSF) grants totaling $2.25 million.  The projects are a four-year, $1.1 million NSF SaTC project and a three-year, $1.15 million NSF BIGDATA project.

Dr. Cheng is the lead PI on the SaTC project, titled “Privacy Attacks and Defense Mechanisms in Online Social Networks.” The project is a collaborative effort with George Mason University and Georgia State University, and Dr. Cheng’s share of the grant is $544,168.  The primary objective of this project is to identify the potential privacy disclosure channels in online social networks and study privacy-preserving countermeasures that suppress access to private information from unauthorized entities without impeding the ability for users to initiate social interactions and share user-created content via online social networks.

The BIGDATA project, which is a collaborative effort with George Mason University, Georgia State University, and Virginia Commonwealth University, is titled “Acquisition, Collection, and Computation of Dynamic Big Sensory Data in Smart Cities.”  Dr. Cheng is a PI on this project, and her share of this grant is $279,107.  The project’s main objective is to develop foundations and technologies for the analytical use of big sensory data to benefit smart cities for monitoring and control.
