Biography

I am currently a Postdoc at the Dept. of Electrical & Computer Engineering, University of Toronto, hosted by Prof. Alberto Leon-Garcia. Prior to my current position, I received my Ph.D. in Electronic and Computer Engineering from Hong Kong University of Science and Technology, advised by Prof. Danny H.K. Tsang. From Oct. 2015 to April 2016, I was also affiliated with the School of Engineering and Applied Science, Harvard University, hosted by Prof. Na Li.

Research Interests

My research interests lie in the mathematical and algorithmic aspects of systems and networks. I explore stochastic models, optimization, mechanism design, and online algorithms to derive insights into the design and management of large-scale systems. Some current applications of interests include: network resource allocation, edge/fog/cloud computing, and energy systems (e.g., electric vehicle charging).

In particular, my current research tends to feature online mechanism design for resource allocation in large-scale systems, where self-interested users compete for resources such as computing cycles, bandwidth, and energy with private preferences. The goal is to design economic incentives and online allocation algorithms so that a desired system-wide performance can be achieved despite the presence of strategic and uncertain user behaviors.
