I'm the RCA Professor of Artificial Intelligence in the Department of Computer and Information Science at the University of Pennsylvania, where I'm also Professor of Linguistics. I received my Ph.D. in 1978 from the MIT Artificial Intelligence Lab, and was a Member of Technical Staff at AT&T Bell Laboratories before coming to Penn in 1987. I served as chair of Penn's Computer and Information Science Department, as chair of the Penn Faculty Senate, as well as president of the Association for Computational Linguistics. I currently serve as chair of the Advisory Committee of the Center of Excellence in Human Language Technology at John Hopkins University. I was named a Fellow of the American Association of Artificial Intelligence in 1992.

I created and ran the Penn Treebank Project through the mid-1990s which developed the primary training corpus that led to a breakthrough in the accuracy of natural language parsers for unrestricted text. I and my collaborators continue to develop hand-annotated corpora for use world-wide as training materials for statistical natural language systems. I am currently the principal investigator for an ARO-funded MURI project to investigate natural language understanding for human-robot interaction with co-PIs at Stanford, Cornell, UMass Amherst, UMass Lowell and George Mason. My research interests include: statistical natural language processing, human-robot communication, and cognitively plausible models for automatic acquisition of linguistic structure.

My past PhD students have gone on to teach at such schools as MIT, Johns Hopkins, University of Arizona, Queens College and the Navy Postgraduate School, and such industrial research labs as IBM Research, BBN Technologies, and Microsoft Research.
