I'm a researcher and a founder fueled by curiosity and a passion for enhancing human learning.
I hold a B.S. in Physics Education and an M.A. in Lifelong Education (Human Resource Development).
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.
In 2025, I built my own research company named MooWee Lab, collaborating with many enthusiastic partners.
