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 such as
(answering natural language questions),
(converting free text into structured relations and events).
I focus mostly on interpretable models, i.e., approaches where the computer can explain
in human understandable terms why it made a decision.

For Spring 2017 I teach Text Retrieval and Web Search (CSC 483/583).
