My primary appointment is with the School of Information: Science, Technology and the Arts (SISTA) at the University of Arizona.
I also moonlight as chief scientist of Lex Machina.
Previously, I was a research scientist in the NLP group at Stanford. 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, when and where),
and other computational linguistics problems.
For Fall 2014 I teach Text Retrieval and Web Search (ISTA 456/556).
