Thesis Research: Automated Data-Driven Hint Generation for Learning Programming
For my thesis work, I ran a series of studies that investigated how we can best design data-driven feedback and hints to help students learn programming. First, I ran a classroom study to investigate student help-seeking needs and beliefs; second, I ran a usability study to determine how different feedback types affected student work; third, I ran a classroom study to determine the actual affect of hints/feedback on learning.

Pre-Thesis Research: ITAP, the Intelligent Teaching Assistant for Programming
We've developed ITAP, a system that takes solution spaces composed of student programs and traverses them to generate next-step hints for students who need help while working.
