General

I'm currently a fourth-year PhD candidate in Department of Electrical Engineering & Computer Science at Northwestern University. I'm co-advised by Professor Dongning Guo and Professor Michael L. Honig .

I received my B.S. degree in Electrical Engineering from Shanghai Jiaotong University (SJTU) in 2013. I was a member of the Teaching Reform Class at SJTU.

Research


My research interests include a variety of topics from wireless communicatoin networks to resource allocation, network optimization, and game theory. Currently I'm working on the following research topics.

1. Allocation of licensed and unlicensed spectrum in large heterogeneous networks.

2. Sparse channel estimation in massive MIMO system.

3. Coexistence between LTE and WiFi in unlicensed spectrum.

4. Hybrid beamforming in millimeter wave networks.
