I am currently pursuing a Ph.D. in the Language Technologies Institute of the School of Computer Science at Carnegie Mellon University. As a Ph.D. candidate, I study theoretical foundations and practical algorithms to approach the meaning of natural language computationally, focusing mainly on event semantics. Specifically, I work on the areas of event detection, event coreference resolution, question answering, information retrieval, question generation, and computer-assisted language learning. I often explore theoretically-grounded combinations of machine-learnable models and knowledge resources for the natural language problems. |

Research Interests
My research interests are in computational semantics, statistical natural language processing, and knowledge representation and reasoning. My general research questions are as follows:
- How can we make computers construct general-purpose and domain-specific semantic resources automatically from natural language sources with the aim of semantically effective natural language processing?
- How can we make computers utilize these resources in concrete natural language processing tasks such as information extraction, dialog management, information retrieval, and question answering?
