I am an Assistant Professor at the City University 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 Edge Lab at Princeton. I have worked at Fraser Research Lab and Qualcomm R&D (QRC). I also did my doctoral work as a Visiting Scholar at the Coordinated Science Lab of UIUC. I am currently serving as the Vice-Chair of the IEEE Information Theory Society Hong Kong Chapter and as an Editor for the IEEE Transactions on Communications.

My research interests include networks, inference in online large data analytics, smart grid, mobile computing, optimization theory and its applications.

I received the 2008 Wu Prize for Excellence from Princeton University and a 2011 IEEE Communications Society Asia-Pacific Outstanding Young Researcher Award.
