Research Interests

My research goal is to advance natural language processing techniques for educational applications. Specifically, I'm interested in analyzing argumentation, learning process, and self-regulation (goal-setting and social comparison) from learners' discussions and essays. In line with this goal, I have developed computational models for analyzing dialogue acts, argument critiques, role modeling in online courses, metaphor detection, etc.

I will teach computer science at Westinghouse High School from this Fall. In the past, I taught Korean at the Carnegie Library of Pittsburgh and tutored middle school students from low-income families in Korea.
