Biography:

I received my BSc (engineering) degree and MSc (engineering) degree from the Department of Electronic Engineering at Shanghai Jiaotong University, Shanghai, China, in 1998 and 2001, respectively. I received my Ph.D. degree from the Department of Electrical and Computer Engineering at the University of Alberta in 2006. All degrees are in the field of communications. I then worked as a postdoctoral fellow in the iCORE Wireless Communications Laboratory at the same department. From 2007 to 2009, I worked as an Assistant Professor in the School of Engineering at the University of Warwick. Currently, I am working as an Associate Professor in the School of Engineering at the University of Warwick.
