I am a Research Assistant Professor at the Institute for AI Industry Research (AIR), Tsinghua University. I received a Ph.D. degree and a Bachelor’s degree in Computer Science, both from Peking University. I had also worked as a Visiting PhD Student at Carnegie Mellon University. Before joining AIR, I was a Senior Researcher in the Systems Research Group at Microsoft Research Asia (MSRA).

My current research interests can be summarized as Edge AI, which includes the following two aspects:

  • Edge AI Efficiency - Building systems to improve the efficiency of AI models, or designing AI models that can run efficiently at the edge.
  • Edge AI Reliability - Improving the reliability of AI models deployed at the edge, by making them more robust, generalizable, and privacy-preserving.

I’ve published more than 20 research papers in premier venues such as ICSE, FSE, ISSTA, SIGIR, UbiComp, MobiCom, MobiSys, and ICLR, including a best paper nomination in UbiComp 2016 and a best paper in IS-EUD 2017. Some of the papers have become popular open-source tools (DroidBot, PrivacyStreams, Humanoid, etc.) in the area.

Our team is recruiting PostDocs, research engineers, and interns. Please feel free to contact me if you are interested.
