I am a professor in the Department of Computer Science at Columbia University. I received my PhD in Computer Science from the University of Pennsylvania, after previously doing teaching (at Smith College) and research in sixteenth-century Mexican social history (PhD from the University of Michigan). I worked at Bell Laboratories and AT&T Laboratories -- Research from 1985-2003 as a Member of Technical Staff and a Department Head. I am an editor-in-chief of Speech Communication and was formerly editor-in-chief of Computational Linguistics, the journal of the Association for Computational Linguistics, from 1993-2003; I was also on the Executive Board of ACL. I have been a fellow of the American Association for Artificial Intelligence since 1994.
