I am currently a Natural Language Scientist at Powerset building a next- generation natural language search engine. I received my Ph.D. in computer science from the University of Southern California, and was doing research with my advisor, Dr. Jerry Hobbs, on several natural language processing and semantic web projects in the Information Sciences Institute (ISI). I have also worked at IBM T.J. Watson Research Center as a research intern.
