My primary appointment is with the Computer Science department at the University of Arizona.
I have a courtesy appointment with Linguistics and Cognitive Science.
Before Arizona, I was a research scientist in the NLP group at Stanford and
chief scientist of Lex Machina.
I did my PhD in computer science at Southern Methodist University.
I work on systems that process and extract meaning from natural language texts, including
(answering natural language questions),
(extracting specific relations and events),
semantic role labeling
(extracting semantic frames that model who did what to whom),
and other computational linguistics problems.

For Fall 2015 I teach Text Retrieval and Web Search (CS 483/583).
