I am a Senior Research Scientist in the Human Machine Interaction (HMI) department at Bosch Research, working in the areas of natural language processing, machine learning, and knowledge representation and reasoning. More specifically, I am interested in the research problems of information extraction, question answering, question generation, and knowledge base construction and utilization. Previously, I obtained a Ph.D. in the Language Technologies Institute of the School of Computer Science at Carnegie Mellon University. Broadly speaking, I am interested in theoretical foundations and practical algorithms to approach the meaning of natural language computationally. 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 semantically oriented natural language processing tasks such as information extraction, dialog management, and question answering?
