I'm a graduate student in the Computer Science and Engineering Department at the University of Washington, working with professor Steve Tanimoto. I received my bachelor's degree in Computer Science from the University of Illinois, at Champaign Urbana, with a minor in Mathematics, in 2003. I received my master's degree in Computer Science from the University of Washington.

My research focuses on designing educational technology, specifically making educational systems more transparent; that is, giving the learner a view inside the program's mind. Say you're using an intelligent tutoring system to learn algebra, working through problems and getting feedback from the tutor. What if you were now given a view into the tutor's mind, and can see why it chooses the problems it does, what it believes about you the learner, how it makes decisions and how it organizes and reasons about information? I'm interested in investigating these questions, with the goal of making educational systems more effective and easier to use.
