Research Topics

1. Computation Capability of Biochemical Reactions

2. Educational Data Mining

Our research interests are focused on theoretical computer science, such as automata theory and computation theory. In particular, we are studying a theory on natural computing theory to explore the information processing mechanisms in natural phenomena, and we are exploring chemical reaction automata, which are computational models in chemical reaction systems.
We also conduct a research in the field of educational data mining. Our contributions include a visualization of students’ learning activities and prediction of students’ performances applying machine learning.
