I am a computer science master student at Johns Hopkins University, where I work with Mark Dredze at Center for Language and Speech Processing. Previously, I have worked with Yong Deng on Complex Network, and Tao Zhou on Human Mobility.

I am interested in Natural Language Processing and Network Science, especially combining them to understand the dynamics of human behaviours in social media and real world.
