I've graduated from Language Technologies Institute, School of Computer Science at Carnegie Mellon University. My thesis advisor was professor William W. Cohen. I worked at Google for 5.5 years on language understanding and question answering. Now I work at SayMosaic as the chief scientist.
I work on machine learning, information retrieval, and natural language processing. Previously I have studied a wide range of topics such as robotic soccer, computer system diagnosis, product search, and question answering. Now I am interested in learning to control machines, and learning to create machines .
