I am currently a third-year Ph.D. candidate in the Department of Electrical and Computer Engineering, University of Toronto. My advisor is Prof. Baochun Li. I received my M.A.Sc degree in Computer Engineering from the University of Toronto, and the B.Eng degree in Information Engineering from The Chinese University of Hong Kong.

I am broadly interested in analyzing, understanding, and improving computer networks, especially its interplay with economics. My current work encompasses cloud computing, datacenters, and wireless networking. I am working on problems at the intersection of networking and economics, such as market driven resource allocation and pricing in the cloud. Previously I have worked on resource allocation in cognitive radio networks and cellular networks using cross-layer optimization and mechanism design.

I enjoy playing basketball, squash, and tennis. My favorite NBA team is Boston Celtics. I jog and do weights training regularly. My favorite dog is German Shepherd.

Short Bio.

I was born and raised in Shaoxing, a tranquil and historical city in southeast China. After high-school, I went to the Chinese University of Hong Kong through the Mainland Undergraduate Intake Programme, and studied in the Department of Information Engineering on full scholarship. After spending four wonderful years in HK, I came to the University of Toronto in 2007. I obtained my M.A.Sc degree in March 2010, and will finish my Ph.D. in 2013.
