RIKEN Center for Advanced Intelligence Project Molecular Informatics Team
Team Director: Koji Tsuda (D.Eng.)
Research Summary

Molecular informatics team aims to develop artificial intelligence methods that design functional biomolecules such as proteins and inorganic compounds such as metal, ceramic and nanoparticles. In addition to theoretical studies about automatic design methods such as Bayesian optimization and Monte Carlo tree search, we synthesize designed materials in collaboration with experimental scientists.
Research Subjects:
- Automatic design methods for molecules and materials
- Automatic construction of materials science databases from literature
- Theoretical studies about experimental design
