I am currently a research developer at Center for Language and Speech Processing in Johns Hopkins University, where I work with Mark Dredze on Computational Social Science and Natural Language Processing. Especially, I used Geotagged Tweets to investigate how people are practicing social distancing in United States, including demographics analysis. I am also working on e cigarettes brands discovery from online forums. I graduated from Johns Hopkins University with M.S.E in Computer Science.

Previously, I have worked with Yong Deng on Complex Network, and Tao Zhou on Human Mobility.

I am applying for PhD starting at Fall 2021.
