About

I'm first year PhD student at Department of Computer and Information Science, University of Pennsylvania.

Currently, I'm working with Prof. Dan Roth on information pollution, and Prof. Mark Yatskar on explaining of visio-linguistic models (e.g. CLIP). I was also fortunate to work with Prof. Derry Wijaya on News Framing during my undergrad at Boston University.

My research interests lie within the theory and applications of NLP. Currently, I'm interested in studying information pollution, perspectives/argument summarization, visio-linguistic applications, and NLP for social good.
