I am a Ph.D.student in Electrical Engineering Department at Columbia University, and I work at the Wim.Net Lab with Professor Gil Zussman. My research interests are in the areas of future wireless networks and systems, including Internet-of-Things (IoT), energy harvesting networks, full-duplex wireless, massive antenna systems, optical-wireless networks, and millimeter-wave networks. In particular, my research focuses on the design and optimization of physical (PHY) layer technologies and Medium Access Control (MAC) layer protocols and their performance evaluation using custom-designed prototypes and testbeds.

I graduated with a B.Eng. degree in Electronic Engineering from Tsinghua University, China, in 2014, and received an M.S. degree in Electrical Engineering from Columbia University in 2015. I am the student co-lead of the Columbia FlexICoN project and am involved in the design and deployment of the NSF PAWR COSMOS testbed. I was also involved in the Columbia EnHANTs project.

I received the Facebook Fellowship, the Wei Family Private Foundation (WFPF) Fellowship, the Columbia Engineering Oscar and Verna Byron Fellowship, and the Columbia University Electrical Engineering Armstrong Memorial Award and Jacob Millman Award. I also received the ACM CoNEXT 2016 Best Paper Award and the ACM MobiHoc 2019 Best Paper Finalist.
