I am a Ph.D. student at Language Technologies Institute, Carnegie Mellon University. My research interest is spoken language understanding. Most recently I work with Jack Mostow on understanding children¡¯s free-form spoken responses in tutorial activities. I also worked with Scott Fahlman on representations of mental states in natural language.
Please see my CV for details of my experience.
