I am currently most excited about the rise of MOOCS (Massive Open Online Courses) such as Coursera and Udacity and how to make use of the massive amount of student data generated by these websites which log, among many other things, every video event, forum interaction, or homework attempt submitted by each student. Not surprisingly, there are a number of probabilistic reasoning problems and combinatorial data types which appear in the "MOOC-alytics" domain. With collaborators, I am working towards highly scalable methods that use machine learning techniques for modeling student behavior and for providing automated or semi-automated informative feedback for complex and open-ended homework assignments.
