My main research interests are information theory, stochastic signal processing and their applications in security, wireless communications and other related areas. I am particularly interested in how to extract, process and transmit useful information securely and reliably. In my research group, we strive to understand the fundamental limits and are also interested in designing practical schemes to approach or achieve these fundamental limits. I received the B.E. and M. E. degrees in Information Science and Electrical Engineering from Zhejiang University, Hangzhou, China in 2001 and 2004 respectively, and the PhD degree in Electrical and Computer Engineering from the Ohio State University at Columbus, OH, in 2007. I was a postdoctoral research associate at the Department of Electrical Engineering, Princeton University from 2007 to 2009. After spending three years as an assistant professor at University of Arkansas, Little Rock from 2009 to 2012, I joined Worcester Polytechnic Institute as an assistant professor in Aug. 2012.
I have received several awards for my work including the Best Paper Award from IEEE Global Communications Conference (Globecom) in 2008, the Best Paper Award from IEEE International Conference on Communications (ICC) in 2011, the Faculty Early Career Development (CAREER) Award from the National Science Foundation in 2011, and the Northrop Young Researcher Award from University of Arkansas, Little Rock in 2012.
