Tongfei Chen

I am a Ph.D. student in the Center for Language and Speech Processing at Johns Hopkins University, working with my advisor Prof. Benjamin Van Durme.

My research interest includes various aspects of natural language processing, especially semantics and knowledge discovery on large corpora. My recent work lies at the crossroads between question answering, information extraction and information retrieval. Before joining Johns Hopkins, I obtained my B.Sc. in Computer Science from Peking University, working with Prof. Junfeng Hu in the Institute of Computational Linguistics with a focus on word segmentation and network analysis.

In addition to natural languages, I'm also interested in the theory of formal languages, especially the design of type systems.

My full CV can be found here.
