Biography

I'm currently an assistant professor at Department of Computer Science and Engineering, Michigan State University. As an assistant professor, I worked in School of Software, Tsinghua University. I received my Ph.D. degree in the Department of Computer Science and Engineering of Hong Kong University of Scienc and Technology. I received my B.E. degree in the Department of Computer Science and Technology of Tsinghua University. My research interests lie broadly in IoT systems, edge computing and mobile computing. Currently, I serve as Associate Editor for ACM Transactions on Sensor Networks (TOSN), which is the flag journal related to computational intelligence in IoT networks.
