I am a Ph.D.student in Electrical Engineering Department, Columbia University, and I work at the Wim.Net Lab with Professor Gil Zussman. My research interests are in algorithms, optimization, MAC layer design, and system implementation in Internet-of-Things (IoT), energy harvesting networksfull-duplex networks, and 5G networks.

I graduated with a B.Eng. degree in Electronic Engineering from Tsinghua University in Beijing, China, in July 2014, and received an M.S. degree in Electrical Engineering from Columbia University, in Oct. 2015. I received the Wei Family Private Foundation (WFPF) fellowship and the Columbia University Electrical Engineering Armstrong Memorial Award. I also received the Best Paper Award from ACM CoNEXT 2016.
