I'm a fourth year Ph.D. student in Computer Science at University of Washington, working with Prof. Arvind Krishnamurthy and Dr. Matthai Philipose. Previously I worked with Prof. David Wetherall and Prof. Aruna Balasumbramanian. I received my bachelor degree in Institute for Theoretical Computer Science (supervised by Prof. Andrew Yao) at Tsinghua University.

Research Projects

  • Mobile Hub: leverages heterogeneous hardware, such as sensor hubs, to improve the power efficiency of always-on sensing applications on mobile phones. MobileHub rewrites the binary of a given application without programmer effort to make it more power efficient.
  • Metasync: a secure and reliable file synchronization service that uses multiple cloud synchronization services as untrusted storage providers. We devised a novel variant of Paxos that provides efficient and consistent updates on top of the unmodified APIs exported by existing services.
  • MCDNN: an approximation-based execution framework for applying computer vision to video on cloud-backed mobile devices using Deep Neural Networks(DNNs). The computational demands of DNNs are high enough that, without careful resource management, such applications strain device battery, and cloud cost budgets. MCDNN allows each request to be served approximately, by systematically trading off DNN classification accuracy for resource use.
