My research is in the intersection of Algorithm Design, Computational Geometry and Networking applications such as wireless, mobile, and sensor networks, and more recently social networks, trajectory data/privacy, and scheduling problems in robotics and networking.
My profile at Google Scholar, Microsoft Academic Search, and DBLP. I work on three projects at the moment.
1. Discrete Curvature of Networks and Graphs.
2. Social Contagions and Influence.
3. Geometric and Topological Analysis for Trajectory Privacy.
I am currently a Professor at Department of Computer Science, Stony Brook University. I received Ph.D degree from Department of Computer Science, Stanford University in 2004, under the guidance of Professor Leonidas Guibas and B.S. degree from the Special Class for the Gifted Young at University of Science and Technology of China in 1999. I spent the academic year 2004-2005 at Center for the Mathematics of Information, California Institute of Technology. I currently serve on the editorital board of ACM Transactions on Sensor Networks and Journal of Discrete Algorithms.
