Hi, I’m Christina Ma, a PhD student at Carnegie Mellon University Human-Computer Interaction Institute, co-advised by Dr. Ken Koedinger & Dr. Sherry (Tongshuang) Wu.
My research interests are in the intersection of LLM and CS education. I design, build, and evaluate LLM‑based educational applications, such as a teachable agent for debugging in CS1 (HypoCompass, AIED24 Best Paper), and an interactive tutor to train prompt programming for end-users (ROPE, TOCHI 2025). My goal is to explore what the optimal human‑AI task delegation is for the future and how to evaluate and train people to work with AI, especially in a programming context. For details of my recent research projects, check out my publications. Here’s my CV.
I got my undergraduate dual degrees of Cognitive Science and Computer Science and a minor in Design for Learning at CMU in 2022. Feel free to learn more about my leadership and educational activities, various writing, technology, design & art projects during undergrad, and some fun facts!
