Broadly I am interested in getting computers to better understand natural language. My research uses machine learning to extract knowledge from large heterogeneous text corpora, for example Twitter and the Web. I received my Ph.D. in Computer Science from the University of Washington and was a postdoctoral fellow in the Machine Learning Department at Carnegie Mellon. Here is a demo of one of my research projects, that automatically extracts a calendar of popular events in the near future from Twitter. A note to prospective students
Postdoc position available!
I have funding to support a postdoc. Contact me if you are interested and think you might be a good fit.
