I am currently a 3rd year Phd student in Computer Science Department
at Dartmouth College,
under supervision of Prof. Xia Zhou in DartNets
Lab. I received my B.E. in Computer Science and B.A. in Digital Art Design in 2012 at Tsinghua
University. I also earned my M.S. in 2015 at Tsinghua University.
My research interests lie in mobile system and wireless networking.

Building Localization via One Smartphone's Photo
SmartGuide is a mobile service on localizing a distant unknown building by taking one photo of it. It detects user's shooting position and shooting direction by recording data of GPS, accelerometer, magnetic sensor. Based on Manhattan World Assumption, some structure information of the target building can be inferred from the photo. At last, we identify the target building on a local Google Map based on above features.
Microsoft Research Asia
iNav aims to generate crowdsourcing semantic maps via rich mobile contextual information and path-based check-ins. Meanwhile, it provides indoor localization service based on crowdsourced maps. The team is composed of researchers from Mobile and Sensing Systems Group, software engineers from Innovation Engineering Group, and UI designers from Human Computer Interaction Group. I was responsible for developing iNav client on Android and improving map crowdsourcing algorithm.
