Michael Hahn

I'm a PhD student in the Stanford NLP Group. I am interested in natural language processing and the cognition of language. Before I came to Stanford, I was at the School of Informatics of the University of Edinburgh, working with Frank Keller. Before that, I studied Mathematics and Computational Linguistics in Tübingen.
