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, focusing on semantics and knowledge discovery on large corpora. My recent work lies at the crossroads between question answering, information extraction and information retrieval.
In addition to natural languages, I'm also interested in programming languages: I design expressive, typesafe DSLs for various domain applications (e.g. deep learning).
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.
