About me

I am a second year Ph.D. student in the Department of Computer Science at Dartmouth College. I am a member of the DartNets (Dartmouth Networking and Ubiquitous Systems) Lab, under the supervision of Prof. Xia Zhou. I received my B.S. in Computer Science and B.A. (minor) in Economics from Peking University in July, 2013. During my senior year, I also went to UCLA as a research-exchange student.

My research interest focuses on mobile systems and wireless networking. Now, I am highly motivated by the topics on VLC (Visible Light Communication) testbed design and spectrum monitoring. Before joining DartNets, I was an undergraduate research assistant at the Center for Energy-efficient Computing and Applications (CECA), Peking University and conducted research on FPGA and Software Defined Radio (SDR) system.


  1. Visible Light Communication (VLC) and Visible Light Sensing

    We build a flexible VLC system and make it a testbed for other researchers to develop new ideas on.

  2. Spectrum Monitering

    We participate in the Microsoft Spectrum Observatory and set up a base station in Sudikoff Lab. Microsoft has recently released a new version. Everyone now has access to the spectrum usage data and raw IQ data collected from stations all over the world.

  3. Wi-Fi Sensing

    Wi-Fi devices are ubiquitous. Human's activities in the space reshape the wireless channel. Therefore, the Channel State Information (CSI) stream reveals human's activity.

I hope that my research improves the respect for individuals.
