I am a fifth-year Ph.D. student in the Stanford University Department of Computer Science. I'm currently on leave from Stanford founding a new video advertising company, AdapTV.

In my academic life I study statistical natural language processing and machine learning with Professor Chris Manning. Recently, my research interests have focused on learning models of linguistic structure using unsupervised and semi-supervised machine learning techniques. I am motivated by the idea that all the text and information on the web ought to be able to help us build better models of language. Don't ask me why, but I like the idea of robots that learn about the world by reading and talking to us!
