I'm a researcher fascinated by exploring the world of knowledge.
My research interests include Data Mining, Measurement, Knowledge Tracing, Natural Language Processing, Causality, Intelligent Tutoring Systems, and Item Response Theory.
Practically, I build systems to evaluate learners' abilities and create useful tools, such as websites and web applications.
If you have any interesting research & development ideas, feel free to contact me via email.
