RIKEN Center for Advanced Intelligence Project Pathology Informatics Team

Team Leader: Yoichiro Yamamoto (M.D., Ph.D.)

Research Summary

Yoichiro  Yamamoto(M.D., Ph.D.)

The mission of Pathology Informatics Team is to discover novel disease mechanisms, to find new therapies or to choose the best treatment for each patient through the combination of the state-of-the-art AI technologies and the medical big data including cell-level information.
Cell-level information in pathology provides the link between the molecular biology and the clinical medicine. Comprehensive analysis of the medical information through collaborations with clinical doctors would contribute to cure current and future patients.
