I am an Assistant Professor at the City University of Hong Kong. Previously, I was a Postdoctoral Scholar at the California Institute of Technology, and affiliated with the Netlab and Rigorous Systems Research Group at Caltech. I graduated from Princeton University in 2008, and was with the CommNet Group at Princeton. I spent the summer of 2005 at Fraser Research Lab working on congestion control algorithms in data networks. I also did my doctoral work as a Visiting Scholar at the Coordinated Science Lab of University of Illinois at Urbana-Champaign, IL, in 2007.

Research Interests: wireless and broadband communications, networking and distributed systems, Green IT, signal processing, information theory and nonlinear optimization.

I am recruiting self-motivating students with a strong mathematical background who are interested in pursuing Master’s or PhD degrees. For graduate application/scholarship information, click here.
