About me

I am currently a third-year PhD student at UCLA CS Department. I am fortunate to work with Prof. Songwu Lu and the amazing members in the Wireless and Networking Group (WiNG). I am excited to explore future mobile networks & applications, including IoT, AR/VR, security and more. Prior to UCLA, I received my B.S. in Computer Science from Peking University. During my undergrad, I also did interesting research over sketch-based algorithms under the supervision of Prof. Tong Yang.
