Caitlin Kelleher is a researcher in Human-Computer Interaction and focuses on designing new kinds of programming environments and languages that democratize programming. Recently, her research group has focused on supporting children learning to program independently. This research has resulted in new kinds of support for tutorials, code execution history exploration tools, and robust support for reusing code from unfamiliar programs. Additionally, her group has explored how to support learning from code puzzles and the kinds of learning decisions young novices make in open ended contexts. The results of this research are shared through the Looking Glass programming environment, available at lookingglass.wustl.edu.
