Generally I am interested in applying semantic knowledge to natural language processing techiques. Currently I am working on dialogue management for intelligent tutoring systems. Of particular relevance to this research are the tasks of characterizing and learning the underlying structure of tutorial dialogue. Related to this work are sub-tasks of question selection, ranking, and generation. Recently I have developed a side interest in data mining for educational contexts. The wide availablity of student data, test scores, and transcripts can help us to better understand the phenomena at work in learning.
